Question

use the periodic table of elements to answer the following question(s). which sentence about the periodic table of elements is true? all elements in period 2 are metals. all elements in group 18 are metals. metals are found on the left side of the periodic table. metals are found on the right side of the periodic table. question 4 1 pts what do the elements sulfur (s), nitrogen (n), phosphorus (p), and bromine (br) have in common? they are noble (inert) gases. they are nonmetals. they have the same thermal conductivity. they have the same number of protons.

Explanation:

1. For the first question: In the periodic table, metals are mainly found on the left - hand side. Period 2 has non - metals like carbon and oxygen. Group 18 elements are noble gases, not metals.
2. For the second question: Sulfur, nitrogen, phosphorus, and bromine are all nonmetals. Noble gases are elements like helium, neon etc. Different nonmetals have different thermal conductivities and different numbers of protons.

Answer:

1. Metals are found on the left side of the periodic table.
2. They are nonmetals.
