When an atom loses an electron, the size will

Back

be smaller.

Front

What are valence electrons?

Back

The number of electrons in the outermost shell.

Front

As atoms of elements in group 16 are considered in order from top to bottom, the electronegativity of each successive element...

Back

decreases.

Front

Electronegativity is...

Back

how good an atom is at attracting electrons.

Front

Ionization energy is...

Back

how much energy it takes to remove an electron from an atom.

Front

What is the trend in atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases.

Front

What happens to the ionization energy as you move across a period from left to right?

Back

Ionization energy increases.

Front

What is the relationship between electronegativity and ionization energy?

Back

Generally, as electronegativity increases, ionization energy also increases.

Front

What are the main factors that affect ionization energy?

Back

Nuclear charge, distance from the nucleus, and electron shielding.

Front

What is the trend in metallic character as you move down a group in the periodic table?

Back

Metallic character increases.
