Answer 1

Silicon- Has properties of both metals and nonmetals
Argon- Nonreactive gas
Bromine- Highly reactive gas
Sodium- Malleable, soft and shiny.

Hopefully this has helped!

Answer 2

Sodium: D

Silicon: C

Bromine: B

Argon: A

Step-by-step explanation:

Hello!!

We can join as follows:

Argon: non-reactive gas. It is a noble gas so its last orbit is complete with electrons, so it is a gas that is not reactive.

Bromine: highly reactive gas.

Bromine at room temperature is a liquid. It is highly reactive and reacts with metals, it is also corrosive.

Silicon: It has properties of both metals and nonmetals. Because of its location in the periodic table, silicon is a metalloid and therefore has properties of metals and nonmetals.

Sodium: malleable, soft and bright. Being a metal, it is malleable.
