6.3 Check for Understanding

Front

An atom with more protons than electrons is a(n) _____

Back

cation

Front

Electronegativity is ____________

Back

the ability of an atom to accept/ attract electrons

Front

As you move across the periodic table, from left to right, ionization energy is __________________

Back

increasing

Front

An atom with 8 protons, 8 neutrons, and 7 electrons is a(n) _________

Back

anion

Front

The ionic radius of metals is ____________

Back

smaller than the metal atom

Front

What is a cation?

Back

A positively charged ion formed when an atom loses one or more electrons.

Front

What is an anion?

Back

A negatively charged ion formed when an atom gains one or more electrons.

Front

Define ionization energy.

Back

The energy required to remove an electron from an atom in a gaseous or ion state.

Front

What trend is observed in electronegativity across a period in the periodic table?

Back

Electronegativity increases from left to right.

Front

What happens to the size of an atom when it forms a cation?

Back

The size decreases because the loss of electrons reduces electron-electron repulsion.
