Front

What are the properties of group 1 metals?

Back

Group 1 metals are characterized by high reactivity and the formation of stable compounds.

Front

Which element has a higher electronegativity than arsenic (As)?

Back

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

Why do atoms get bigger as you move down the periodic table?

Back

Atoms get bigger because they have more energy levels.

Front

What is electronegativity?

Back

Electronegativity is a measure of the ability of an atom to attract electrons.

Front

What happens to ionization energy as you move across a period?

Back

Ionization energy generally increases as you move from left to right across a period.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius decreases as you move from left to right across a period and increases as you move down a group.

Front

What is a cation?

Back

A cation is a positively charged ion.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
