What happens when an atom become an ion with a 2-change?

+2 or -2? Either way, nothing special happens.


What change in electron structure occurs when magnesium atom becomes a magnesium ion?

When a magnesium atom becomes a magnesium ion, it loses two electrons from its outermost shell, resulting in a positively charged ion (Mg²⁺). This change in electron structure transforms the neutral magnesium atom, which has 12 electrons, into an ion with only 10 electrons. Consequently, the ion achieves a stable electron configuration similar to that of neon, with a full outer shell.


Wta happens whenan atom forms an ion?

When an atom forms an ion, it gains or loses electrons, resulting in a positive or negative charge. A positively charged ion is called a cation, and a negatively charged ion is called an anion. This change in the number of electrons affects the atom's chemical properties and reactivity.


What change in electron structure occures when a sodium atom becomes a sodium ion?

The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.


What happens when atom looses electron?

If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.


How does a hydrogen ion change into an atom?

A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.


What happens to the structure of an atom to change it into an ion?

An atom becomes an ion when it gains or loses one or more electrons, resulting in a net electrical charge. If an atom loses electrons, it becomes a positively charged cation, while gaining electrons turns it into a negatively charged anion. This alteration in the number of electrons affects the overall charge of the atom, but the number of protons in the nucleus remains unchanged. Consequently, the ion's chemical properties and reactivity differ from those of the neutral atom.


What is the Lewis structure of the cyanide ion?

The Lewis structure of the cyanide ion (CN-) consists of a carbon atom bonded to a nitrogen atom with a triple bond, and a lone pair of electrons on the nitrogen atom.


Can you draw the Lewis structure for a nitric oxide ion?

The Lewis structure for a nitric oxide ion (NO) has a nitrogen atom in the center with a single bond to an oxygen atom and a positive charge on the nitrogen atom.


The Lewis structure for a barium Ba ion looks like this Ba2 what best describes what happens when a barium atom forms an ion?

When a barium atom forms an ion, it loses two electrons to achieve a stable octet configuration like a noble gas. This results in the formation of a Ba2+ ion with a 0 oxidation state.


How does an atom change to a negatively charged ion what happens to the subatomic partieles?

An atom gains a negative charge by gaining extra electrons. When this happens, the atom becomes an ion. The number of protons in the nucleus remains the same, but the number of electrons increases, leading to an overall negative charge.


What happens to an atom if it gains an electron will it be a negative ion or positive ion?

It will be a negative ion, or in other words, a anion.
