Calcium
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
Potassium has 19 protons, 19 electrons and 20 neutrons.
11 protons and 9 neutrons
In a neutral atom of calcium-41 (⁴¹Ca), the atomic number of calcium is 20, which means it has 20 protons and 20 electrons. The mass number is 41, which represents the total number of protons and neutrons. To find the number of neutrons, subtract the number of protons from the mass number: 41 - 20 = 21 neutrons. Thus, ⁴¹Ca has 20 protons, 21 neutrons, and 20 electrons.
The isotope (^{43}_{20}\text{Ca}) (calcium-43) has 20 protons, which is characteristic of all calcium atoms. To find the number of neutrons, subtract the atomic number from the mass number: (43 - 20 = 23) neutrons. Since it is a neutral atom, it also has 20 electrons. Thus, calcium-43 has 20 protons, 23 neutrons, and 20 electrons.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
An isotope of the element with 20 protons and 20 neutrons is calcium-40. Calcium has an atomic number of 20, which means it has 20 protons. The total number of protons and neutrons in calcium-40 is 40 (20 protons + 20 neutrons).
It has 20 neutrons.
A calcium atom typically has 20 protons, 20 electrons, and approximately 20 neutrons.
Calcium has 20 neutrons and is found in your teeth.
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
20 neutrons.
20 neutrons
Potassium-39 has 20 neutrons. This is because the atomic number of potassium is 19, which represents the number of protons in its nucleus. Subtracting the atomic number from the atomic mass gives you the number of neutrons.
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass. For calcium with an atomic number of 20, if the atomic mass is 40, then the number of neutrons would be 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
