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.

How many protons neutrons and electrons will positive two ion of calcium have?

A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.


How many protons neutrons and electrons does Ca have?

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.


How many neutrons are in calcium -41?

There are 20 neutrons in calcium-41, which is determined by subtracting the atomic number (20, representing number of protons) from the mass number (41, representing total number of protons and neutrons).


How many neutrons does Calcium - 45 have?

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.


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 is an isotope of the element with 20 protons and 20 neutrons?

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).


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 electrons and neutrons dose calcium have?

Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.

How many protons does calcium 47 have?

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


The mass number of an atom of calcium with 20 protons and 20 neutrons is?

The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.


What does calcium contain?

Um, the element calcium? Protons, neutrons, electrons..


How many neutrons are in calcium -41?

There are 20 neutrons in calcium-41, which is determined by subtracting the atomic number (20, representing number of protons) from the mass number (41, representing total number of protons and neutrons).


What are the elements that formed the calcium?

Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.


What is the element that has 20 neutrons?

Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
