Best Answer

Ca (2+) I think because since there are two less electrons then the charge would become positive.

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 in the element kalsium?

1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons


A positive two ion of calcium ca plus 2 would have how many protons electrons and neutrons?

20 protons, 18 electron's, and 20 neutrons


How many protons electrons neutrons are in a molecule of carbon dioxide how many in a molecule of calcium nitrate?

Carbon Dioxide has the formula of CO2, which means 1 Carbon atom and 2 Oxygen atom per CO2 molecule. Carbon12 has 6 protons, 6 neutrons and 6 electrons per atom. Oxygen has 8 protons, 8 neutrons and 8 electrons per atom. One CO2 molecule contains 22 protons, 22 neutrons and 22 electrons. Calcium Nitrate has the formula of Ca(NO3)2. Calcium contains 20 of each. Nitrogen contains 7 of each. Oxygen contains 8 of each. Per molecule there are 1 calcium, 2 Nitrogen and 6 oxygen. Therefore: 20 + (2x7) + (6x8) = 20 + 14 + 48 = 72 protons, 72 Neutrons and 72 electrons. I hope that answers your question.


What is the number of protons and neutrons in a calcium nucleus?

The atomic number of calcium is 20 and relative atomic mass (nucleon number) 40.1. The nucleon number is a decimal because it is an average value having taking all the different isotopes into consideration, based on their relative abundance. So all calcium atoms have 20 protons and 20 electrons. The number of neutrons will depend on what isotope of calcium we are talking about; calcium has 24 isotopes. If we consider the isotope calcium-40, which is the most abundant of all at about 97%, the can determine its number of neutrons as 40 - 20 = 20. So a calcium-40 isotope has 20 neutrons.

How many neutrons are in a calcium ion?

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

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.)


What element has twenty neutrons?

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


How many protons neutrons and electrons does calcium ion have?

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.


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
