Transcript text: An atom or ion has 43 neutrons, 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number and charge for this atom or ion. element symbol: $\square$ mass number. $\square$ charge: $\square$

Solution

Solution Steps

Step 1: Identify the Element Symbol

The element symbol is determined by the number of protons. The number of protons is 36, which corresponds to the element Krypton (Kr) on the periodic table.

Step 2: Determine the Mass Number

The mass number is the sum of the protons and neutrons in the atom or ion. Given 36 protons and 43 neutrons: \[ \text{Mass number} = 36 + 43 = 79 \]

Step 3: Determine the Charge

The charge of the atom or ion is determined by the difference between the number of protons and electrons. Since there are 36 protons and 36 electrons, the charge is: \[ \text{Charge} = 36 - 36 = 0 \]
