Question

Match the atom to the number of electrons it is likely to gain/lose.Beryllium (Be)?lose 1Chlorine (CI)?lose 2Nitrogen (N)?lose 3Oxygen (0)?gain 3Aluminum (AI)?gain 2Sodium (Na)?gain 1

Answer 1

Explanation:

Alkali metals: Lithium, sodium, potassium, rubidium, cesium, and francium.

These metals tend to lose 1 electron.

Alkaline Earth Metals: Beryllium, magnesium, calcium, strontium, barium, and radium.

These metals tend to lose 2 electrons

----------------------

Elements like nitrogen, oxygen, and chlorine, tend to gain electrons. These are nonmetals

----------------------

According to the task:

Answer:

Beryllium loses 2 electrons

Chlorine gains 1 electron

Nitrogen gains 3 electrons

Oxigen gains 2 electrons

Aluminum loses 3 electrons

Sodium loses 1 electron
