Back

periodic law

Front

What is Group 2A on the periodic table?

Back

alkaline Earth metals

Front

What is the significance of valence electrons in determining chemical properties?

Back

Valence electrons determine how an element reacts chemically with other elements.

Front

Define the term 'periodic table'.

Back

A tabular arrangement of the chemical elements, organized by increasing atomic number and grouped by similar properties.

Front

What are alkali metals?

Back

Elements in Group 1A of the periodic table, known for being highly reactive and having one valence electron.

Front

What are noble gases?

Back

Elements in Group 18 of the periodic table, known for being inert and having a full valence shell.

Front

What is the periodic law?

Back

The principle that the properties of elements are a periodic function of their atomic numbers.
