Calcium-41 has 21 neutrons.
Calcium is a metal element. Atomic mass of it is 40.
41 protons 41 electrons 52 neutrons
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
it depends on the isotopes of calcium e.g. Calcium-40 has 20 electrons and 20 neutrons Calcium-44 has 20 electrons and 24 neutrons To find out the number of neutrons for Calcium you take the Isotope number (x) minus away the number of electrons (20) e.g. Calcium-x Calcium-x has 20 electrons and (x-20) neutrons.. OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons
Calcium-45 has 20 protons (since it is calcium) and therefore, it has 25 neutrons, as the atomic number (number of protons) subtracted from the mass number (protons + neutrons) gives the number of neutrons.
A neutral atom of calcium with a mass number of 41 would have 20 protons since calcium has an atomic number of 20. To find the number of neutrons, you subtract the atomic number from the mass number, so there would be 21 neutrons in this atom.
Calcium is a metal element. Atomic mass of it is 40.
20 neutrons
The most stable isotope, calcium-40 has 20 neutrons.
This isotope don't exist.Added:That's right, the element with atom number 41 has 41 protons and should be :Naturally occurring niobium which is composed of one stable isotope, 41Nb(93)This means that the mass number (= total of protons AND neutrons) is 93!, so this isotope of Nb has 93-41 = 52 neutrons!As of 2003, at least 32 radioisotopes have also been synthesized, ranging in atomic mass from 81 to 113, so they have 40 to 82 neutrons. This makes the amount of 20 neutrons erronous.However: if the question were 'inverted' to:"What element has 21 (not 41) protons and 20 neutrons" instead, there is a possible more realistic question.The answer to this is: scandium, 21Sc(41) This unstable isotope of Sc, with mass number 41, has 21 protons and 20 neutrons.
41 protons 41 electrons 52 neutrons
calcium has 20 neutrons and electrons
Potassium-41 has 19 electrons and protons and 22 neutrons.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element; each isotope of calcium has a different number of neutrons. See the link below for calcium isotopes.
There are 20 neutrons in an atom of Calcium.
