An atom that has lost two electrons is called?
This atom become a cation with the electrical charge +2.
What ions came from an atom that lost two electrons?
An atom that loses two electrons will form a cation with a +2 charge. For example, sodium can form a Na+ cation by losing two electrons.
What happens when an atom becomes an ion with a 2 charge?
When an atom becomes an ion with a 2+ charge, it means that the atom has lost two electrons, resulting in more protons than electrons. This gives the ion a positive charge since protons are positively charged particles. The ion will now be attracted to other particles with a negative charge to achieve stability through the formation of ionic bonds.
What are two ways electrons can be gained or lost from an atom?
An electron can be gained or lost from an atom for two reasons: 1. A random number of atoms can be close together will have electrons bumping into each other. Since all electrons have a negative charge, they will have magnetic effects on one another, and will push eachother of the outer shell of their atoms and into different ones. 2.Two or more atoms can bond together so that both atoms in turn have a balanced number of electrons.
What is the charge of nickel when two electrons are lost?
The charge of nickel when two electrons are lost is +2. When nickel loses two electrons, it becomes a cation with a charge of +2.
An atom that has lost two electrons is called?
This atom become a cation with the electrical charge +2.
What is the charge on an atom of copper that has lost two electrons and how is this ion represented?
+2 is the charge represented Cu2+
Are electrons in group 2 lost or gained?
They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
When does an atom become an ion with a charge of 2 plus?
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.

What charge will an atom have if it loses an electron?
As written, there's some ambiguity in the question, but the answer is probably "+2" assuming the atom was neutral to start with and that the two outer-shell electrons were the only electrons lost.
What is the difference between an electrically charged atom or a electrically balanced atom?
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An uncharged atom of oxygen has 8 protons and 8 electrons. Sometimes it gains two electrons. This means that it has 8 protons but 10 electrons. +8 -10 = -2. therefore the charged atom of oxygen has a charge of -2.

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 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.
