Question

question 1 / 1
what is the sodium ions charge?
it has 11 protons.
it has 12 neutrons.
it has 10 electrons.

a. +1
b. -1
c. +11

Explanation:

Step1: Recall ion charge formula

The charge of an ion is calculated as the number of protons minus the number of electrons, i.e., \( \text{Charge} = \text{Number of Protons} - \text{Number of Electrons} \).

Step2: Substitute values

Given, number of protons \( = 11 \), number of electrons \( = 10 \). Substitute into the formula: \( \text{Charge} = 11 - 10 = 1 \). Since protons are positive and electrons are negative, having more protons gives a positive charge, so the charge is \( +1 \).

Answer:

A. +1
