What is the charge on a magnesium ion that has 10 electrons?

Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.


What charge would an oxygen atom with 10 electrons have?

An Oxygen atom would never contain 10 electrons on its own. It would have a maximum of 8 electrons at one time, unless the "oxygen atom" you are referring to is in fact an oxygen ION, in which case the charge would be -2. However, an oxygen ion can never be "by itself". It must be bonded with either itself as a diatomic or with another element as a compound.


An atom has 10 protons in its nucleus and 10 electrons in orbit around the nucleus Frictional forces temporarily srtip away two of the electrons The net charge on this atom is?

+10 + (-8) = +2+10 + (-8) = +2+10 + (-8) = +2+10 + (-8) = +2


What charge does 2 electrons have?

2 unbalanced electrons have a 2- charge on the molecule/atom


How many electrons does 24mg2 have?

The symbol "24mg2" likely refers to the magnesium ion with a +2 charge. Magnesium has 12 electrons in a neutral atom, but since it has a +2 charge, it has lost 2 electrons, giving it 10 electrons in total when it becomes a Mg2+ ion.


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.


When an atom becomes a ion with a 2- charge the atom?

an ion with a 2- charge has 2 more electrons than usual


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.


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.


If a calcium atom has 20 protons and 20 neutrons and 18 electrons what is the magnitude of it's charge in coloumbs?

The charge of a calcium atom with 18 electrons will be +2 elementary charges since it has 20 protons and 18 electrons, resulting in a net positive charge. Each elementary charge is approximately 1.602 x 10^-19 Coulombs, so the total charge of the calcium atom would be 2 * 1.602 x 10^-19 Coulombs.


When an atom becomes an ion with a negative 2 charge the atom?

Gained 2 electrons


How does the balance of protons and electrons determone whether an atom is electrically charged?

If the number of protons is the same as the number of electrons, the atom is Neutral (the +'s and the -'s cancel out, leaving no net charge). If there are more electrons than protons, then the atom is negatively charged. If there are more protons than electrons, then the atom is positively charged. A Helium atom has 2 protons and 2 electrons: ++ --: No net charge: Neutral. A Chloride ion has 17 protons and 18 electrons: 17+ 18 -: Net charge -1: Negative (anion). A Sodium ion has 11 protons and 10 elections: 11+ 10-: Net charge +1: Positive (cation.
