Question

question 2 (1 point) listen given the following numbers of protons (p), neutrons (n), and electrons (e), which of the following could be isotopes of silicon (si)? a) 16 p, 16 e, 15 n b) 14 p, 14 e, 14 n c) 16 p, 16 e, 12 n d) 15 p, 15 e, 13 n e) 14 p, 14 e, 15 n

Explanation:

Isotopes of an element have the same number of protons (equal to the element's atomic number). Silicon has an atomic number of 14, so any silicon isotope must have 14 protons. Neutral atoms have equal numbers of protons and electrons, so these isotopes will also have 14 electrons, with varying numbers of neutrons.

Answer:

b) 14 p, 14 e, 14 n
e) 14 p, 14 e, 15 n
