How many neutrons does 40 20ca have?
20 neutrons
The number of neutrons can be obtained by subtracting the number of protons (Z) from the total number of particles in the nucleus (A): 126C: N = A – Z = 12 – 6 = 6 neutrons. 4020Ca: N = 40 – 20 = 20 neutrons. (The same applies to 4020Ca2+.

Calcium-40/Protons
How many neutrons and electrons does calcium 42 have?
Click to see full answer. Accordingly, how many protons neutrons and electrons does calcium 42 have? Answer and Explanation: A calcium atom has 20 protons, 20 electrons and 20 neutrons. what is the number of protons in calcium? 20
Is the number of electrons and protons in an atom the same?
No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it’s actually possible to have an atom consisting of only a proton (ionized hydrogen). For a neutral atom, the number of electrons is the same as the number of protons.
How many electrons does a neutral atom have?
The only change in the number of subatomic particles between the atom and its ion is in the number of electrons. The number of protons of a neutral atom and its ion is the same. 40Ca and 40Ca2+ both have 20 protons. 40Ca has 20 electrons.
How many protons are in an atom of calcium?
In this case, calcium’s atomic number is 20; thus one atom has 20 protons. If the question specifically states that the particle is an atom, then we know it’s neutral as opposed to a charged ion.
