Question

14 multiple choice 1 point science what is the number of protons in an atom with the electron configuration of 1s²2s²3p³? 5 2 3 7

Explanation:

Step1: Calculate the number of electrons

For a neutral atom, the number of protons equals the number of electrons. Calculate the number of electrons from the electron configuration \(1s^{2}2s^{2}2p^{3}\).
The sum of the exponents gives the number of electrons: \(2 + 2+3\).

$$2 + 2+3=7$$

Answer:

7
