These two elements are most likely good conductors of heat and electricity and shiny when solid.

a. au and br
b. b and i
c. sn and ag
d. p and se

Option (C) is the correct answer.

Explanation:

Metals are the substances which lose electrons in order to gain stability.

Some properties of metals are as follows.

Gold (Au) is a metal but bromine (Br) is a non-metal.

Boron (B) is a metal but iodine (I) is a non-metal.

Both phosphorous (P) and Selenium (Se) are non-metals.

Tin (Sn) is a metalloid and it shows properties of both metals and non-metals. Also, silver (Ag) is a metal.

Therefore, both tin and silver are good conductors of heat and electricity and shiny when solid.

Thus, we can conclude that out of the given options Sn and Ag two elements are most likely good conductors of heat and electricity and shiny when solid.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
