Answer
a. 56 protons, 54 electrons
b. 30 protons, 28 electrons
c. 7 protons, 10 electrons
d. 37 protons, 36 electrons
e. 27 protons, 24 electrons
f. 52 protons, 54 electrons
g. 35 protons, 36 electrons
Work Step by Step
The number of protons is equal to the atomic number of the element, this can be looked up from periodic table.
The number of electrons will be equal to number of proton in neutral atom but a single positive charge means that there one electron less than number of proton and a single negative charge means that it have one electron more than number of proton. So the number of electrons can be calculated as number of protons - charge of ion.
We have:
a. 56 protons, 54 electrons
b. 30 protons, 28 electrons
c. 7 protons, 10 electrons
d. 37 protons, 36 electrons
e. 27 protons, 24 electrons
f. 52 protons, 54 electrons
g. 35 protons, 36 electrons
