The mass number of an atom of calcium with twenty protons and twenty neutrons?

The mass number of an atom of calcium with twenty protons and twenty neutrons is 40. This is because the mass number is the sum of the protons and neutrons in the nucleus of an atom.


How many protons and electrons does a calcium atom have?

Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.


What are the subatomic particles of calcium?

Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20


How many protons neutrons and electrons are in an atom of calcium-42?

An atom of calcium-42 has 20 protons, as calcium has an atomic number of 20. Since the atomic number represents the number of protons in an atom, calcium always has 20 protons. Calcium-42 also has 22 neutrons, calculated by subtracting the atomic number from the atomic mass (42 - 20 = 22). The number of electrons in a neutral atom is equal to the number of protons, so a calcium-42 atom would have 20 electrons.


How many protons (p) neutrons (n) and electrons (e) are in an atom of calcium?

There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.


How many protons does calcium 47 have?

mass number = number of protons + number of neutrons. 47 = 20 + neutrons, so neutrons equal 27.


How many protons and neutrons are there in electronic configuration of the atom of calcium?

The number of protons in a calcium atom is always the same as the atomic number of calcium, which is 20. The number of neutrons depends on the isotope. The most common isotope is Ca-40. The number of neutrons is equal to the isotopic mass number minus the atomic number, in this instance, also 20.


What is the symbol for an atom that has 20 protons and 22 neutrons?

The atom with 20 protons and 22 neutrons would be Calcium (Ca) with atomic number 20 and mass number 42 (20 protons + 22 neutrons).


An atom of an element contains 20 protons 20 neutrons and 20 electons This element is?

Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.


What is tha neutron for calicum?

An atom contains protons, neutrons, and electrons. The electrons are tiny. They can be found in a fast-moving cloud, orbiting the nucleus. Each electron has a charge of -1. The nucleus contains the protons and neutrons, which are packed tightly together. The protons each have a charge of +1, and the neutrons have a charge of zero. The mass number of an element is the number of protons and the number of neutrons added together. Since the number of protons is equal to the atomic number of the element, the number of neutrons can be found by subtracting the atomic number from the mass number.


What element's neutral atoms have 20 protons?

it is about the atomic number. Calcium is the element.


How many protons are in an isotope of calcium with a mass number of 42?

A calcium isotope with a mass number of 42 would have 20 protons since calcium always has 20 protons. The mass number includes both protons and neutrons, so subtracting the number of neutrons (mass number - number of protons) gives the number of protons.
