What is it called when a atom gains electrons to become a negative ion?

This depends on whether the atom is by itself or whether it's part of a molecule (attached set of atoms).
If it is by itself, after the atom gains (or loses) an electron it has an electrical charge. An atom with a charge is called an "ion" and you can say that it was "ionized."
If it is in a molecule that has a chemical reaction with another molecule causing the atom in the first molecule to gain an electron, that process is called "reduction," and the atom that gained an electron is said to have been "reduced." If the atom lost an electron in the reaction, that is called "oxidation" and the the atom was "oxidized." (Note that "oxidation" in regular chemistry doesn't necessarily mean that oxygen was involved, even though it sounds that way.)

∙ 13y agoThis particular reaction is called an Ionic Bond. Ionic Bonds occur when an atom has a higher electronegativity of at least 2. This allows the higher electronegative atom to completely pull the electrons it wants from the other atom, resulting in two ions, hence the name Ionic Bond.

What causes an atoms to become positively or negatively charged?
The ratio of electrons (negative) to protons (positive.). An atom is nutruel in normal condition. It has positive proton and negative electron in a balanced form.when electrons emit from atoms than a positive charge form in atom. And vice versa.
What ion is form when an atom gains electrons?
Typically, a negative ion is formed by gaining electrons. This is because electrons hvae a negative charge. An example of a case where a positive ion can be formed by gaining an electron is when an ion with a charge of +2 can gain 1 electron and become +1. Technically in this case, a positive ion was formed when an electron was gained but the trend was that the ion became more negative not positive.
What is the resulting charge of a surface that gains electrons?
Electrons have a negative charge. Therefore, an atom having extra electrons is a negative ion.
What results after an atom gains electrons?
Electrons have a positive charge and protons have a negative charge. An atom's nucleus is 99.95% of its weight. When an object gains more electrons, it gains a negative charge that over comes the positive charge. This only happens when there are more electrons than protons.
What happens when an element gains electrons?
If a neutral atom gains one or more electrons, then it will have a negative change. If a positive atom gains electrons, it will have an increase in change, but the charge may be negative, neutral, or positive based on the initial charge and number of electrons gained. The process in which an atom gains electrons is known as reduction.
What form when atoms lose or gain electrons and become positively or negatively charged?
If you are asking what it is called, when an atom looses or gains electrons it is called an ion. Electrons are negative, so when an atom looses electrons it becomes more positive and is called an cation. So, when an atom gains electrons it becomes more negative and is called an anion.
Will an object become positivley or negatively charged if it gains electrons?
An atom will become Negative if it gains an electron and it will be an Anion.If it loses an electron it will be Positive and it will be a CationLearn & Enjoy
The charge an object has when it has gained electrons?
electric charge
What do you call an atom that gains or loses electrons?
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
If oxygen gains 2 electrons what charge will it have?
It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
When an atom gains electrons it becomes positively charged true or false?
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
What does an atom become when it gains an electrons in an ionic bond?
a negative ion... this was Ben McClanahan for you A+ people out there :))
What is a neutral atom that gains or loses electrons?
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
When one atom gives up an electron to another atom what does it form?
When an atom gains or loses one or more electrons, it forms an ion. If it loses electrons, it becomes a positively charged ion called a cation. If it gains electrons, it becomes a negatively charged ion called an anion.
Why reduction reaction is called reduction?
Because it gains electrons ,therefore its valency decreases : it becomes Negative
What are negative charged ions are called?
Ions that have negative charges are called anions. Anions form when a non metal gains electrons lost from a metal.
When a sodium atom gains or loses a valence electron it becomes a charged particle called an?
Atoms that gain or lose electrons are called ions. If it gains one or more electrons it becomes negative it is called an anion. If it loses one or more electrons and becomes positive it is called a cation.
