Question

A)Why does the reactivity of metals increase from right to left on the periodic table?(1 point)

Responses

Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.
Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.

Metals on the right have fewer protons, making it harder to attract electrons from other atoms.

Here are the correct responses to your questions:

Question 1: Why does the reactivity of metals increase from right to left on the periodic table?
Response: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.

Question 2: How do nonmetals tend to form bonds?
Response: by gaining electrons

Question 3: Which feature is unique to Group 18 nonmetals?
Response: They are very nonreactive.

Question 4: Which of the following combination of elements is the most reactive?
Response: Cs and Br (Rubidium (Rb) and Bromine (Br) are highly reactive due to Rb being an alkali metal and Br being a halogen, and cesium (Cs) is even more reactive than rubidium.)

Question 5: How does Rb bond with other elements?
Response: Rb loses an electron.
