NATIONAL PERIODIC TABLE DAY
National Periodic Table Day is observed annually on February 7.
To understand the development of the periodic table, we first must understand the discovery of elements and their effect on science.
Elements known to ancient man were few. Gold, silver, copper, iron, lead, tin, mercury, sulfur and carbon were the earliest known elements. These were all known prior to the 1st century A.D.
Over time, arsenic, antimony, phosphorus and zinc were discovered. By 1809 there were 47 discovered elements.
One of the earliest attempts to organize the elements was by Johann Döbereiner in 1817. He organized elements into groups of three, or triads, based on similar qualities.
On February 7, 1863, English chemist John Newlands published one of the first table of elements, which divided the known 56 elements into 11 groups based on the “Law of Octaves.” This suggested that any one element will have similar properties to elements eight places before and behind it on the table.
Arranging the elements according to increasing atomic weight, Newlands was one of the first scientists to detect a pattern to the properties of elements. As a result, his table left room for new discoveries, predicting future discovered elements would complete the table. Newlands correctly predicted the discovery of Germanium.
While parts of Newlands periodic table had flaws, so did other later proposed tables. In 1869 chemist Dimitri Mendeleev published a paper developing a periodic table arranging the elements also based on atomic mass. By this time only 60 of the over 100 elements we know today were discovered.
There were also some inaccuracies attributed to some of those elements. While Mendeleev corrected some of these inaccuracies, he made assumptions about others causing elements to be placed incorrectly on the table. Like Newlands, Mendeleev predicted discoveries as well. He correctly predicted the properties of five elements and their compounds.
The discoveries throughout Scot William Ramsay’s career from 1892 to 1910, along with John William Strutt, Morris Travers and Frederick Soddy led to the identification of the noble gasses. Ramsay was awarded a Nobel Prize in 1904 for discovering five elements.
Henry Moseley, an experimental physicist, contributed to the development of the modern periodic table when he discovered in 1913 that each element has a specific number of protons. As a result, four new chemical elements were later found, though not during his lifetime.
Since the early 20th century there have been very few significant changes to the periodic table. The 21st century is still young, though and some researchers have suggested new approaches to the periodic table while maintaining its integrity as one of the most valuable tools in the science of chemistry. The current table tallies a total of 118 elements.

Educators, visit the National Day Calendar Classroom pages for ways to incorporate National Periodic Table Day into your classroom.
National Periodic Table Day was founded on February 7, 2016, with the goal of promoting the challenges that were overcome to develop the modern periodic table. Mr. David T. Steineker, author, inventor, and chemistry teacher at Jefferson County Public Schools in Kentucky is inspired by those challenges and took the initiative to celebrate National Periodic Table Day based upon John Newlands first table of the elements published on February 7, 1863.
NATIONAL SEND A CARD TO A FRIEND DAY
We often think about our friends. We wonder how they are, miss them and remember fond memories of times shared. Always observed on February 7th, National Send A Card To A Friend Day is the day to send our friends a card and let them know that we are thinking of them!
It is always a pleasant surprise to receive a card from a friend.
HOW TO OBSERVE
Send a card to your friends. With the technology we have, we can also send Ecards. You can buy cards at a store, or you can make them yourself. Whichever way you choose, set aside a few minutes to write a short note or a long note in a card and send one to make a friend’s day! Use #SendACardToAFriendDay to post on social media.
Within our research, we were unable to identify the creator of National Send a Card to a Friend Day.
NATIONAL FETTUCCINE ALFREDO DAY
National Fettuccine Alfredo Day is observed annually on February 7th.
Alfredo di Lelio, an Italian restaurateur, created Fettuccine Alfredo in 1908. After his wife had given birth to their first son that year, she did not have an appetite. To help encourage her to eat, he created a dish of noodles, cheese and butter. She liked the dish so much that she thought he should put it on the menu at his small restaurant in Rome. Everyone around the world has been enjoying this dish ever since. Today it is one of the most popular pasta dishes in America.
HOW TO OBSERVE
You can enjoy this delicious pasta at a favorite restaurant or try this delicious recipe at home: Primo Fettuccine Alfredo recipe.

We have learned the history of Fettuccine Alfredo. However, research has failed to find the creator of this day.
A special update from the Grandson of the founder of Fettuccine Alfredo
History of Alfredo Di Lelio, creator in 1908 of “Fettuccine All ‘Alfredo” (Fettuccine Alfredo), now served by his nephew Ines Di Lelio, at the restaurant “Il Vero Alfredo” – “Alfredo Di Roma” in Rome, Piazza Augusto Imperatore 30
With reference of your article (for which I thank you), I have the pleasure to tell you the history of my grandfather Alfredo Di Lelio, who is the creator of “Fettuccine all’Alfredo” (“Fettuccine Alfredo”) in 1908 in the “trattoria” run by his mother Angelina in Rome, Piazza Rosa (Piazza disappeared in 1910 following the construction of the Galleria Colonna / Sordi).
This “trattoria” of Piazza Rosa has become the “birthplace of fettuccine all’Alfredo”. More specifically, as is well known to many people who love the “fettuccine all’Alfredo”, this famous dish in the world was invented by Alfredo Di Lelio concerned about the lack of appetite of his wife Ines, who was pregnant with my father Armando (born February 26, 1908). Alfredo di Lelio opened his restaurant “Alfredo” in 1914 in Rome and in 1943, during the war, he sold the restaurant to others outside his family. In 1950 Alfredo Di Lelio decided to reopen with his son Armando his restaurant in Piazza Augusto Imperatore n.30 “Il Vero Alfredo” (“Alfredo di Roma”), whose fame in the world has been strengthened by his nephew Alfredo and that now managed by me, with the famous “gold cutlery” (fork and spoon gold) donated in 1927 by two well-known American actors Mary Pickford and Douglas Fairbanks (in gratitude for the hospitality). See also the website of “Il Vero Alfredo”.(with news also about franchising). I celebrate every year (as this year) in my restaurant (founded by my grandfather Alfredo Di Lelio) the USA Holiday of. fettuccine all’Alfredo (February 7). I must clarify that other restaurants “Alfredo” in Rome do not belong to the family tradition of “Il Vero Alfredo – Alfredo di Roma”. I inform you that the restaurant “Il Vero Alfredo –Alfredo di Roma” is in the registry of “Historic Shops of Excellence” of the City of Rome Capitale.
Best regards Ines Di Lelio
