This atom become a cation with a +2 electrical charge. All atoms have are neutral because the numbers of protons and electrons are equal. When you subtract any number n of electrons, the new charge is +n, just as a general rule.

improved answer:
electrons will always have a negative charge.
When an ion Gains an electron, they Gain a Negative Charge (-1)
When an ion Loses an electron, they Lose a negative charge (+1)
This is proportional to the number of electrons gained or lost (gain 2 electrons, -2 charge), and what the original ion's charge was.
Original Charges:
An ion will always have a positive or negative charge, and it is predictable on the Periodic Table what that charge is. (Groups are the vertical columns)
Group 1 = +1
Group 2 = +2
Group 4 = -4
Group 5 = -3
Group 6 = -2
Group 7 = -1
So F which is found in group 7 has a natural charge of -1, if it loses an electron it will be (-1 initial charge) +1(losing a negative charge) = 0.

An atom that has lost two electrons is called?
This atom become a cation with the electrical charge +2.
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
What is the ionic charge of neutral calcium that contains 20 protons 20 neutrons and 20 electrons and loses two electrons?
A neutral calcium atom that loses two electrons has a +2 charge.
What happens when an atom becomes an ion with a 2 charge?
Let's say that an Oxygen (O) has a charge of -2. O-2 is no longer called an atom because it has a charge. It is now called an ion. It is said as Oxygen negative 2 ion. It means that the atom's number of electrons increased by 2.
What is the Definition and formation of cations and anions?
An ion is an atom which is not neutral i.e. it has excess of charge on it. There are two types of ions:Cation:- These have positive charge on them. They are formed when an loses electrons and protons exceed their number.Anion:- These have negative charge in them. They are formed when an atom gains electrons and no. of electrons exceed the no. of protons.
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.
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+
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.
An atom that has lost two electrons is called?
This atom become a cation with the electrical charge +2.
Is it true or false that an alpha particle has a double positive charge because it is a helium atom that has lost two electrons?
It is true
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.
Is the following true or false An alpha particle has a double charge because it is a helium atom that has lost two electrons?
True, it lost its only two electrons, which makes it consist of 2 protons and 2 neutrons
How is the cation Ion formed?
A CATION is a positively charged ion . e.g. Na^(+) The sodium metal has IONISED by losing one electron to form the CATION. (Na^(+)). Similarly calcium metal ionises by losing two electrons to form the CATION Ca^(2+). NB An ANION is a NEGATIVELY charged ion e.g. Cl^(-) Cations and Anions are collectively known as 'Ions'. So your statement 'Cation ion' is incorrect. You just need the word 'cation'.
If there are two electrons in an atom how many protons would be in the atom?
The atom in a normal state would have two protons to match the two electrons, making the overall charge zero. If the atom is an ion, it would have an mismatched number of protons and electrons, giving it a positive or negative overall charge.
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.
What is the net charge of a copper atom if it gains two electrons?
Copper loss electrons.
Which electrons in a magnesium atom are most likely to be lost?
Magnesium atoms have two electrons in their outer shell; it is these that will be lost, to turn the Mg atom into an Mg2+ ion.
