The Periodic Table

Match the following

• halogen

• Oxygen

• non-metal

• Bromine

• alkali earth metal

• Calcium

• noble gas

• Xenon

• transition metal

• Copper

Metals will always form

• cations

• anions

Answer explanation

Metals tend to lose electrons due to their low electronegativity, resulting in the formation of positively charged ions known as cations. Therefore, metals will always form cations.

Calcium is a(n)...

• alkali metal

• transition metal

• alkali earth metal

• halogen

Answer explanation

Calcium is classified as an alkali earth metal, which is found in Group 2 of the periodic table. This group includes elements that are known for their reactivity and the presence of two electrons in their outer shell.

Phosphorus is a(n)...

• alkali metal

• nonmetal

• halogen

• transition metal

Answer explanation

Phosphorus is classified as a nonmetal because it typically lacks the properties of metals, such as high electrical conductivity and malleability. It is found in group 15 of the periodic table, which is known for its nonmetals.
