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.
Potassium has 19 protons, 19 electrons and 20 neutrons.
This isotope has 20 protons and and electrons and 22 neutrons.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Calcium-48 has 20 protons, 28 neutrons, and 20 electrons. The number of protons defines the element as calcium, while the mass number (48) is the sum of protons and neutrons, indicating it has 28 neutrons (48 - 20 = 28). Since it is a neutral atom, the number of electrons equals the number of protons.
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.
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.
There are 19 protons,20 neutrons, and 19 electrons.
