ru 4-
ru 4-
ru
ru 4+
ru 4+

for iodine - 131 with a chemical symbol and net charge of i - what is the atomic number

Explanation:

Step1: Identify the element by proton number

The number of protons determines the element. With 44 protons, the element is Ruthenium, symbol Ru.

Step2: Calculate the net charge

Net charge = number of protons - number of electrons. Given 44 protons and 40 electrons, net charge = 44 - 40 = +4.

Answer:

Ru 4+
