Question

an ion from a given element has 13 protons and 10 electrons. what is the charge on the ion? what is the name of the element? what is the symbol for the ion?

Explanation:

Step1: Determine the element

The number of protons determines the element. With 13 protons, the element is aluminum (Al).

Step2: Calculate the charge

Charge = Number of protons - Number of electrons. Given 13 protons and 10 electrons, Charge = 13 - 10 = + 3.

Step3: Write the ion symbol

The ion symbol is written with the element symbol and the charge as a superscript. So it is $Al^{3 + }$.

Answer:

What is the name of the element?: Aluminum
What is the charge on the ion?: +3
What is the symbol for the ion?: $Al^{3 + }$
