Question

question 1 of 10
why do all the elements in group 16 share similar properties?
a. they all have the same number of valence electrons.
b. they all are in the same period of the periodic table.
c. they all have electrons the same distances from their nuclei.
d. they all have the same number of protons.

Explanation:

Elements in the same group of the periodic table have the same number of valence electrons, which determines their chemical - bonding behavior and many chemical properties. Elements in the same period have the same number of electron shells but different numbers of valence electrons. Electron - nucleus distances vary with the number of electron shells and nuclear charge. The number of protons is unique to each element and defines the element's identity.

Answer:

A. They all have the same number of valence electrons.
