If calcium lost two electrons it would have the same number of electrons as?

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.


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.


How many electrons are gain or lost to form ions for calcium?

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.


A cation of calcium has a 2 plus charge how many electrons does it have?

calcium has 20 electrons.when it loses 2 electrons, it has 18 electrons.


What is the chemical symbol for calcium that has lost 2 electrons?

The chemical symbol for calcium is Ca. When calcium loses 2 electrons, it forms a 2+ cation, written as Ca²⁺.


How many electrons are lost when ca plus 2 is formed?

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.


How many electrons are present in 40Ca2?

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.


In chemical notation Ca2 plus means what?

calcium ions that has lost electrons. It will give away electrons.


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 electrons must be gained or lost for calcium to attain a noble-gas electron configuration?

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.


How many electrons does a stable calcium ION have?

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.


In chemical notation, the symbol Ca2+ means?

a calcium ion that has lost two electrons.
