Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
Calcium has atomic number 20. A neutron calcium atom therefore has 20 protons and 20 electrons. Ca2+ has a charge of positive 2, so it must have 2 more protons than electrons. Ca2+ has 18 electrons.

3He has 2 protons, 1 neutron, and 2 electrons.
20 protons and 20 electrons are present in calcium.
None. Protons and electrons are not constituents of a neutron. Both neutrons and protons are constituents of an atom's nucleus (core), while the electrons are situated in the electronic cloud around the nucleus.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.

20 protons, 20 electrons, and usually 20 neutrons
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
there are 9 protons and there are 19 neutrons and 17 electrons. plz contact me on facebook.com/gennamerryman
