Ca (2+) I think because since there are two less electrons then the charge would become positive.
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
1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus.The protons have a positive charge, the neutrons have no charge, and the electrons have a negative charge.
A calcium ion with a charge of +2 has lost 2 electrons, resulting in an electron count of 18. Since calcium has an atomic number of 20, the number of protons remains at 20. To find the number of neutrons, subtract the number of protons (20) from the mass number (which can be found on the periodic table), which for calcium is 40, to get 20 neutrons.
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.
calcium has 20 neutrons and electrons
A calcium atom typically has 20 protons, 20 electrons, and approximately 20 neutrons.
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
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
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
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.
Um, the element calcium? Protons, neutrons, electrons..
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.
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.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
Calcium has twenty protons and twenty electrons. The main isotope of calcium also has twenty neutrons.
