carbon has :
36000 protons
124000 electrons
348850 calcium
A neutral carbon atom has 6 protons and 6 electrons.
Calcium (element number 20) has 20 protons and 20 electrons.
20 protons and 20 electrons are present in calcium.
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
6 electrons, protons, and neutrons.
6 protons, 6 electrons and 6 protons in carbon-12 atom
20
20 protons, 20 electrons, and usually 20 neutrons
Carbon has 6 protons. In a neutral atom, the number of protons is equal to the number of electrons, which is why carbon, with 6 electrons, also has 6 protons. This is what defines it as the element carbon on the periodic table.
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.
if its not an ion it has 6
