Front

What is the definition of valence electrons?

Back

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

Front

How do you determine the number of protons in an atom?

Back

The number of protons in an atom is equal to its atomic number.

Front

What is the significance of the period number in the periodic table?

Back

The period number indicates the number of energy levels in the atoms of the elements in that period.

Front

How many total electrons are in a neutral atom of Calcium (Ca)?

Back

20 (since the number of electrons equals the number of protons in a neutral atom).
