2 Answers. The magnesium ion Mg2+ is formed when the magnesium atom loses the two electrons from its outer shell! to form a stable ion with a noble gas configuration.
How many electrons does magnesium Mg need to lose to have the same number of electrons as one of the noble gases?
Metals form positive ions (cations). A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+.
How many electrons must Mg lose to become a noble gas?
2 Answers. The magnesium ion Mg2+ is formed when the magnesium atom loses the two electrons from its outer shell! to form a stable ion with a noble gas configuration.
How many electrons does magnesium have?
The most common and stable type of magnesium atom found in nature has 12 protons, 12 neutrons, and 12 electrons (which have a negative charge).
How many electrons do elements lose?
All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions.
What are the 2 most stable ions magnesium can make?
Which is more stable magnesium atom or magnesium ion? Mg is more stable because it is neutral atom while Mg ^+2 to be stable will loses two electrons readily.
What would a magnesium atom be called if it loses 2 electrons?
Magnesium is in Group 2. It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2 + , is formed. A magnesium ion has the same electronic structure as a neon atom (Ne).
Why does magnesium have 12 electrons?
Once one shell is full, the next electron that is added has to move to the next shell . ... That means there are 12 electrons in a magnesium atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and two more in shell three.
How are the electrons in magnesium arranged?
In writing the electron configuration for Magnesium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for magnesium go in the 2s orbital. The nex six electrons will go in the 2p orbital
How many protons and electrons are in Fe3+?
Difference of number of electrons from number of protons defines the charge on an atom. For example, among atoms of iron, all with 26 protons, Fe2+ has 24 electrons and Fe3+ has 23 electrons , whereas elemental (uncharged) Fe has 26 electrons.
Can an atom lose 5 electrons?
So I understand that an atom can gain or lose electrons and still retain it's identity – for example a Carbon atom is still carbon even if it loses 5 of it's 6 electrons because it is the number of protons that make it what it is.
Can lose or gain electrons?
Sometimes atoms gain or lose electrons . The atom then loses or gains a “negative” charge. These atoms are then called ions. Positive Ion – Occurs when an atom loses an electron (negative charge) it has more protons than electrons.
How many electrons can you gain?
Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons.
Which ion is the most stable?
And since cyanide has the highest stability, we can say that $Fe(CN)_{6}]^ {3-}$ is the most stable ion.
What is the most stable ion of fluorine?
Neutral atom of Fluorine has 7 valence electrons. To acquire noble gas configuration it has only 1 less electron so it gains 1 electron and complete its valence shell and acquire stable configuration so the most stable mono atomic
What is the most stable ion of barium?
Barium can obtain the stable arrangement of 54 electron losing two of its elecrons,forming the Ba2+ cation .
