Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does Hydrogen have?

Back

1 Valence electron.

Front

How many valence electrons are found in atoms of group 14?

Back

4 Valence electrons.

Front

What is the preferred number of electrons in the valence shell for most stable atoms?

Back

8 electrons.

Front

How many valence electrons does Aluminum have?

Back

3 Valence electrons.

Front

How many electrons does Hydrogen need in its valence shell to be stable?

Back

2 electrons.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms are most stable when they have eight electrons in their valence shell.

Front

What is an electron dot diagram?

Back

An electron dot diagram is a visual representation of the valence electrons in an atom, using dots around the element's symbol.

Front

Which group of the periodic table has 1 valence electron?

Back

Group 1 (alkali metals) has 1 valence electron.

Front

What happens to an atom's stability when it achieves a full valence shell?

Back

An atom becomes more stable when it achieves a full valence shell, typically with 8 electrons.
