An electron in the third shell has more energy than the electron in the second shell.

Electrons in higher energy shells of a calcium atom are farther from the nucleus and have more energy than electrons in lower energy shells. This is because as the energy level of a shell increases, the distance from the nucleus also increases, resulting in higher potential energy for the electrons.

How many neutrons are in a calcium ion?
In a typical calcium ion, there are 20 neutrons. This is because the atomic number of calcium is 20, indicating the number of protons in the nucleus, and the number of neutrons is usually the same in a neutral atom of calcium.
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 many electrons on the outermost shell of calcium?
There are 2 electrons in the outermost shell of calcium. Calcium is in group 2 of the periodic table, so it has 2 valence electrons.
If calcium is most happy with a charge of 2 how many electrons would it have?
A calcium atom has 20 electrons. To achieve a charge of +2, calcium will lose 2 electrons, leaving it with 18 electrons.
How many valence electron does calcium have?
Calcium has 2 valence electrons, like all Group 2 elements.
What is number of electrons for calcium?
A neutral atom of calcium has 20 electrons
How many electrons does calcium have in the periodic table?
Calcium has 20 electrons in the periodic table.
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
How many neutrons are in a calcium ion?
In a typical calcium ion, there are 20 neutrons. This is because the atomic number of calcium is 20, indicating the number of protons in the nucleus, and the number of neutrons is usually the same in a neutral atom of calcium.
How many electrons in calcium?
There are 20 electrons in a calcium atom.
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 many electrons are calcium?

How many valence electrons have calcium?
Calcium has two valence electrons.
How many nuetrons and electrons does calcium have?
calcium has 20 neutrons and electrons
Calcium valence electrons are?
Calcium has a total of two valence electrons.
State the number of valence electrons in an atom of calcium?
An atom of calcium has 2 valence electrons.
What scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
