How many protons neutrons and electrons does calcium ion have?
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 electrons are in a calcium atom and in a calcium ion?
A calcium atom has 20 electrons, as it has 20 protons to maintain a neutral charge. A calcium ion, specifically Ca2+, has lost two electrons, so it has 18 electrons.
A positive two ion of calcium Ca would have how many protons electrons and neutrons?
A positive calcium ion (Ca^2+) has 20 protons, 18 electrons, and 20 neutrons. This is because the atomic number of calcium is 20, indicating 20 protons in a neutral atom, and losing 2 electrons makes it positively charged while the number of protons and neutrons remains the same.
How many protons electrons and neutrons does a positive two ion for calcium?
20 p+ 20 n
What makes up calcium-40 ion with a charge of 2 plus?
Calcium-40 with a 2+ charge has lost two electrons, making it a Ca2+ ion. This ion contains 20 protons, as in all calcium atoms, and 18 electrons (since it lost two electrons).
How many protons in positive two ion of calcium?
The same number as in an atom of Ca, the same as the atomic number of Ca. An ion will have a different number of electrons than protons, so it is not 20. Only neutral atoms have the same number of electrons as protons, which is the same as the atomic number. A calcium ion (Ca+2) has two less electrons than protons (having lost two to fulfill the octet rule), so it has 18 electrons.
How many electrons do calcium has?
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
How is are the configurations of calcium and a calcium ion similar?
They are the same in that they have the same number of protons and neutrons. However, the number of electrons is different. The calcium 2+ ion has two less electrons than the normal calcium atom.
How many subatomic particles does an ion of calcium with an atomic number of 20 and an atomic mass of 40 hve?
atom have: 20 protons,20 electrons and20 neutrons ion have: 20 protons 18 electrons( metals lose electrons) and20 neutrons
How many protons does an atom of Calcium have in its nucleus?
A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the number of electrons is 18; 20 - 18 = +2. The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20.
If a calcium atom has twenty protons then how many electrons would it have?
20 (any more or less and it would be an ion not an atom)
