The number of protons in an element does not depend on the charge of the element. An atom of a given element has the same number of protons as an isotope of that element. Thus, a calcium ion has 20 protons, just like atoms in calcium metal.
When a calcium ion (Ca^2+) is formed, two electrons are lost. This is because calcium has 20 protons and electrons in its neutral state, but when it loses two electrons to form Ca^2+, it now has 18 electrons.
Magnesium has 12 protons. Bear in mind that ionization has no effect on the number of protons, so the "2 plus" is unnecessary. Magnesium always has 12 protons, that is the definition of magnesium.
A positive calcium ion (Ca^2+) has 20 protons, 18 electrons, and 20 neutrons. This is because the atomic number of calcium is 20, indicating 20 protons in a neutral atom, and losing 2 electrons makes it positively charged while the number of protons and neutrons remains the same.
I don't want to do your homework for you. Here's how you figure it out: Protons = atomic number Neutrons = atomic mass - atomic number Electrons = atomic number + ionization
Ca is Calcium It's Atomic Number is 20. So it has 20electrons. so 20+2=22 wala
It has 20 protons, irrespective of its charge.
The number of protons is 2.
When a calcium ion (Ca^2+) is formed, two electrons are lost. This is because calcium has 20 protons and electrons in its neutral state, but when it loses two electrons to form Ca^2+, it now has 18 electrons.
The number of protons is 2.
The ion carbon C4+ has 6 protons and 2 electrons.
Lead will always have 82 protons. If it has a 2+ charge, that means there are 2 more protons than electrons, so there are 80 electrons.
Magnesium has 12 protons. Bear in mind that ionization has no effect on the number of protons, so the "2 plus" is unnecessary. Magnesium always has 12 protons, that is the definition of magnesium.
The atomic number of hafnium is 72. So there is 72 protons.
A positive calcium ion (Ca^2+) has 20 protons, 18 electrons, and 20 neutrons. This is because the atomic number of calcium is 20, indicating 20 protons in a neutral atom, and losing 2 electrons makes it positively charged while the number of protons and neutrons remains the same.
Ca(OH )2 plus sulfuric acid yields water and CaSO4.

In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
