Detailed explanation-1: -So we have to find out anything more is in that atom. So a neutral atom contain equal number of positively charged servatory particle actori particle. That is proton and negatively charge, or we can say that it is electron…
Detailed explanation-2: -Neutrons, along with protons, are subatomic particles found inside the nucleus of every atom. The only exception is hydrogen, where the nucleus contains only a single proton. Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons.
Detailed explanation-3: -This is a magnesium Ion. There are 12 protons from the magnesium atom. There are 10 electrons because 12-2 = 10.
Detailed explanation-4: -Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge.
Detailed explanation-5: -The symbol for magnesium is . Magnesium has an atomic number of 12 and a mass number of 24. So a magnesium atom has 12 protons, 12 electrons, and 12 neutrons.
