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.
i believe 2+ <--this is right, see below
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.
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.
The charge is 2+
Negative (:
This atom become a cation with the electrical charge +2.
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
A neutral calcium atom that loses two electrons has 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.
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.
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.
+2 is the charge represented Cu2+
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.
This atom become a cation with the electrical charge +2.
It is true
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.
True, it lost its only two electrons, which makes it consist of 2 protons and 2 neutrons
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'.
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.
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.
Copper loss electrons.
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.
