2 electrons are lost from calcium, forming Ca2+ ion
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
A calcium atom loses 2 electrons to form a Ca2+ ion. This is because calcium has 20 electrons in its neutral state, and it becomes more stable by losing these 2 outer electrons to achieve a full valence shell.
When a calcium ion (Ca^2+) is formed, two electrons are lost. This is because calcium has 20 protons and electrons in its neutral state, but when it loses two electrons to form Ca^2+, it now has 18 electrons.
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
A stable calcium ion has lost two electrons, resulting in a total of 18 electrons. Calcium typically has 20 electrons in its neutral state, but when it loses two electrons to form a Ca2+ ion, it maintains stability by having a full outer electron shell.
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
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.

calcium has 20 electrons.when it loses 2 electrons, it has 18 electrons.
The chemical symbol for calcium is Ca. When calcium loses 2 electrons, it forms a 2+ cation, written as Ca²⁺.
When a calcium ion (Ca^2+) is formed, two electrons are lost. This is because calcium has 20 protons and electrons in its neutral state, but when it loses two electrons to form Ca^2+, it now has 18 electrons.
A calcium ion with a 2+ charge (Ca2+) has lost two electrons. A neutral calcium atom (Ca) has 20 electrons, so Ca2+ would have 18 electrons.
calcium ions that has lost electrons. It will give away electrons.
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).
