Front

As you move down the periodic table, atoms get bigger because ____________.

Back

The atoms have more energy levels.

Front

The tendency of an atom to attract electrons and acquire a negative charge is called ____________.

Back

Electronegativity.

Front

Electronegativity is defined as ____________.

Back

How good an atom is at attracting electrons.

Front

How many valence electrons does Beryllium have?

Back

2.

Front

The minimum energy required to remove an electron from the ground state of an atom is known as ____________.

Back

Ionization energy.

Front

What is the periodic trend for atomic size as you move across a period from left to right?

Back

Atomic size decreases.

Front

What is the periodic trend for ionization energy as you move down a group?

Back

Ionization energy decreases.

Front

What is the relationship between electronegativity and atomic size?

Back

As atomic size increases, electronegativity generally decreases.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of the octet rule in chemistry?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
