Easiest to understand while looking at a Periodic Table. As you know, all gases react to try to become nobles. Magnesium has 12 electrons, and the closest noble gas (neon), which Mg wants to become, has 10 electrons. So in order to be balanced, Mg has to lose 3 electrons (you may initially think it needs to lost 2, but include Mg when you are counting back --> 12,11,10) . When an atom loses electrons, which have a negative charge, it will become positive, as it will have more positive H+ atoms than negative e- atoms. Again, if you look at your periodic table, this is quite simple to figure out :)
What else can I help you with?
What is the charge on an atom of magnesium?
The neutral atom of magnesium has no electrical charge; the ion is bivalent.
What charge are neutrons in the magnesium atom?
All neutrons have a negative charge. That is the reason they are called neutrons.
What will be the final charge of magnesium ion when it has lost its 2 electrons?
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⁺.
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 charge of magnesium when it forms an ion?
Magnesium as an atom has two valance electrons. To complete it's octet, it must lose two electrons. Losing two electrons will make Mg have 12 protons and 10 electrons therefore having a +2 charge.
What is the charge on an atom of magnesium?
The neutral atom of magnesium has no electrical charge; the ion is bivalent.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
What charge are neutrons in the magnesium atom?
All neutrons have a negative charge. That is the reason they are called neutrons.
Magnesium protons and 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.
What is the formula for a Magnesium Ion?
The formula for a magnesium ion is Mg2+. This indicates that the magnesium atom has lost two electrons, giving it a positive charge of 2.
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 will be the final charge of magnesium ion when it has lost its 2 electrons?
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⁺.
What would the charge on a neutral magnesium atom be?
Well, if it's neutral.... It's kinda a no brainer.
Is the magnesium atom electrically neutral or electrically charged?
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.
A magnesium ion differs from a magnesium atom because 1. two fewer neutrons. 2. one fewer electron. 3. one more electron. 4. two fewer electrons.?
A magnesium ion differs from a magnesium atom because it has two fewer electrons. When a magnesium atom loses two electrons, it forms a magnesium ion with a 2+ charge.
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.
How many protons does the magnesium cation have?
The periodic table states that the atomic number of magnesium is 12. A magnesium atom would thus have 12 protons in its nucleus; any atom that has 12 protons must be a magnesium atom. Atomic number = number of protons
