Question

exam 1
which of the following is a characteristic of the group 14 elements?
o they have 14 neutrons
o they have 4 valence electrons.
o they have 4 core electrons
o they have 14 protons

Explanation:

Group 14 elements (carbon - family) have 4 valence electrons. The number of neutrons varies among isotopes, the number of core electrons depends on the element's position in the period, and only silicon has 14 protons (not all Group 14 elements).

Answer:

They have 4 valence electrons.
