Chemistry Chap. 5: Periodic Table (Def. & Review)

Ductility is the ability of a metal to bend or be hammered into a flat sheet without breaking.

• True

• False

Elements are placed into groups (vertical columns) based on their electron configurations. This led to the formation of the modern periodic table.

• True

• False

Noble gasses are sometimes called inert because they rarely take part in a reaction.

• True

• False

There are seven periods on the periodic table; this corresponds with the 7 energy levels.

• True

• False

You can determine an atom’s electron configuration and its number of valence electrons from its position on the periodic table.

• True

• False

Anions are always larger than the atoms from which they form. As the number of electrons increases, the electrostatic repulsion between the outer electrons increases.

• True

• False

Atoms of metals tend to form ions by gaining electrons to their outer energy level.

• True

• False

During reactions between metals and nonmetals, metal atoms tend to gain electrons and nonmetal atoms tend to lose electrons.

• True

• False

The p sublevel can hold how many electrons?

• 2

• 6

• 10

• 14

The f sublevel can hold how many electrons?

• 2

• 6

• 10

• 14
