History

Founding

The Alpha Chi Sigma fraternity was organized at the University of Wisconsin-Madison in late 1902 by a group of undergraduates who were fellow students in chemistry at that time. Later documents set the date of founding as December 11, 1902. The original founders were: “University of Wisconsin” redirects here. ... 1902 (MCMII) was a common year starting on Wednesday (see link for calendar). ...

Coat Of Arms

The seven symbols that stretch the length of the coat of arms are the "seven metals of the Ancients": gold, silver, iron, mercury, tin, copper, and lead. These symbols correspond to planets, gods, and days of the week [1]. GOLD refers to one of the following: GOLD (IEEE) is an IEEE program designed to garner more student members at the university level (Graduates of the Last Decade). ... General Name, Symbol, Number silver, Ag, 47 Chemical series transition metals Group, Period, Block 11, 5, d Appearance lustrous white metal Standard atomic weight 107. ... General Name, symbol, number iron, Fe, 26 Chemical series transition metals Group, period, block 8, 4, d Appearance lustrous metallic with a grayish tinge Standard atomic weight 55. ...

General Name, Symbol, Number lead, Pb, 82 Chemical series Post-transition metals or poor metals Group, Period, Block 14, 6, p Appearance bluish gray Standard atomic weight 207. ...

The rest of the symbols on the coat of arms are revealed only to those that go through the initiation ritual. This ritual secrecy is common practice among fraternities and sororities in the United States. The terms fraternity and sorority (from the Latin words and , meaning brother and sister respectively) may be used to describe many social and charitable organizations, for example the Lions Club, Epsilon Sigma Alpha, Rotary International, Optimist International, or the Shriners. ...

Purpose

The Three Objects of Alpha Chi Sigma:

1. To bind its members with a tie of true and lasting friendship.
2. To strive for the advancement of chemistry both as a science and as a profession.
3. To aid its members by every honorable means in the attainment of their ambitions as chemists throughout their mortal lives.

Membership

Membership to the Alpha Chi Sigma professional chemistry fraternity is open to collegiate and professional men and women with a strong interest in chemistry. Membership is for life. Those who are interested in becoming a member should contact their local (or nearest) chapter for further information about pledgeship and membership.
