What do all groups/families in the periodic table have in common?

Back

Properties

Front

What happens to the atomic radius as you move from left to right across the periodic table?

Back

The atomic radius decreases because the number of protons increases, leading to a stronger attraction to electrons.

Front

What type of ion does an atom become when it loses a valence electron?

Back

Positive ion

Front

Arrange the following elements in order of increasing ionization energy: Strontium, Aluminum, Indium.

Back

Strontium, Indium, Aluminum

Front

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

Back

Ionization energy decreases as you move down a group.

Front

What is the trend in electronegativity as you move across a period from left to right?

Back

Electronegativity increases as you move from left to right across a period.

Front

Define atomic radius.

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

What is the general trend of metallic character in the periodic table?

Back

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

Front

What is the relationship between atomic number and the number of protons in an atom?

Back

The atomic number of an element is equal to the number of protons in its nucleus.
