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

This number is 40.


What element has twenty neutrons?

Calcium has twenty protons and twenty electrons. The main isotope of calcium also has twenty neutrons.


How many protons does an atom with an atomic number of twenty-four and a mass number of fifty-one have?

The atomic number is equal to the number of protons in the atom. Therefore, if an element has an atomic number of 24 (which in this case is chromium) then it has 24 protons. The mass number is the sum of the number of protons and neutrons.


How does an atom Argon-38 compare to an ordinary Argon-36 atom?

Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.


What is the isotope of atom?

An isotope atom of an element is one with the same number of protons in the nucleus (i.e the atomic number) but with a different number of neutrons giving it a different mass. Isotopes have the same chemistry because they have identical valence shells. An example is chlorine which is found in nature with two stable isotopes 35Cl with 18 neutrons and 37Cl with twenty. As 35 is around 75% and 37 25% in nature the atomic weight is 35.453.


What is the atomic number of an atom with twenty six protons?

The atomic number is based on what?

It is based on number of protons. Consider an element has 20 protons.Its atomic number is twenty.


What is the mass number of an isotope if it has an atomic number of twenty five?

Manganese or Mn has an atomic number of 25 (25 protons). The stable atom has 30 neutrons, so the stable atomic mass is 55 amu. The mass for one of its isotopes depends on how many neutrons it has. For instance, the next most stable isotope of Mn is Mn53 with only 28 neutrons so it has an atomic mass of 53 amu.


How many neutrons does a chlorine atom have in its nucleus in words?

The number of neutrons is different for each isotope. Chlorine-35 has eighteen neutrons. Chlorine-36 has nineteen neutrons. Chlorine-37 has twenty neutrons. ....... etc.


What is the atomic based on?
