Well, if it's neutral.... It's kinda a no brainer.
The neutral atom of magnesium has no electrical charge; the ion is bivalent.
A neutral atom with 12 protons will have 12 electrons in order to balance the positive charge from the protons.
The magnesium atom is electrically neutral. It has 12 protons in the nucleus, which are positively charged, and 12 electrons surrounding the nucleus, which are negatively charged. The positive and negative charges balance each other out, resulting in an overall neutral charge for the atom.
When a neutral magnesium atom loses two electrons, it becomes a magnesium ion (Mg²⁺). Since electrons carry a negative charge, losing two electrons results in a net positive charge of +2 on the magnesium ion. Therefore, the net electrical charge on a magnesium ion is +2.
Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.
A neutral atom will have a charge of ZERO
Such an atom would be neutral - no electric charge.
It an atom has 12 electrons and is neutral, then it must be Mg (magnesium), and magnesium has 2 valence electrons which would be used in bonding.
Neutral atom of magnesium has 12 electrons.
A magnesium atom has 12 protons, 12 electrons, and 12 neutrons. Protons carry a positive charge, electrons a negative charge, and neutrons have no charge. The number of protons determines the element (in this case, magnesium), while the number of electrons balances the positive charge of the protons to maintain a neutral atom.
The oxygen atom is neutral.
When magnesium loses its two electrons, it forms a magnesium ion with a charge of +2. This occurs because the neutral magnesium atom has 12 protons and 12 electrons, and losing two electrons results in a net positive charge. Therefore, the final charge of the magnesium ion is +2, represented as Mg²⁺.
