Potassium (K) is a highly reactive metal on the periodic table. It readily forms compounds with nonmetals. How does valence electrons and stability work in chemical bonding?

Potassium has 1 valence electron that it can lose easily. When it loses the electron, it achieves stability because it has a full outer energy level.

Potassium has 2 valence electrons that it can lose easily. When it loses the electrons, it achieves stability because it has a full outer energy level.

Potassium has 6 valence electrons that it can lose easily. When it gains two electrons, it achieves stability because it has a full outer energy level.

Potassium has 7 valence electrons that it can gain one easily. When it gains the electron, it achieves stability because it has a full outer energy level.

What will this lewis structure bond with?

an element with two valence electrons

an element with one valence electron

an element with four valence electrons

An unknown element has 7 protons and similar chemical properties to Phosphorous (P) and Germanium (Ga). Which of the following statements is true about this unknown element?

The unknown element is Nitrogen (N) and it has 5 valence electrons

The unknown element is Nitrogen (N) and it is a metal

The unknown element is Arsenic (As) and it is a metal

The unknown element is Arsenic (As) and it has 5 valence electrons

Which of the following is true about the periodic table?

Elements in the same groups have the same properties and reactivity

Elements in the same period have the same properties and reactivity

All metals have the same chemical properties and reactivity

All metalloids have the same chemical properties and reactivity

Which elements have the least chemical reactivity?

Beryllium, Magnesium, and Calcium

Describe the reactivity of group 18 elements?

nonreactive because they have a full outer shell

extremely reactive because they have 8 valence electrons
