the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.

What part of an atom is important in bonding?

The electrons in an atom are important in bonding because they are involved in forming chemical bonds with other atoms. By sharing or transferring electrons with other atoms, atoms can achieve a more stable configuration.


What is an atom called when it gain an electron?

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.)


Are Ions charged atoms or groups of atoms?

Either one. You can have an ionized atom or an ionized molecule. Many ionized molecules are radicals that had been part of a larger molecule and the event that separated them also ionized the radical. This is what free radicalsare.


What is the smallest part or fragment of an atom?

The smallest part or fragment of an atom is the Electon.

What is the only part of the atom that can be rubbed or pulled off?

The only part of an atom that can be removed or added is an electron. Electrons are negatively charged particles that can be gained or lost during chemical reactions.


What is different between atom and ion?

An ion is an atom that has either gained or lost electrons. An ion has either a positive or negative charge, depending on whether it gained electrons (negative) or lost electrons (positive), while an atom is electrically neutral. When not part of a molecule, elements usually exist in an ionic form, the exception being the noble gases, or the elements on the leftmost column of the periodic table.


How many electrons are in the element with the symbol Y?

Yttrium (Y) has, for the most part, 39 electrons. In its ion (atom with a charge that has lost or gained electrons) form though, it has 36 electrons.

What is the different between atoms and ions?

An Ion makes up the electric charge of an atom. It can be a positively (+) charged atom or a negatively (-) charged atom, depending on the number of protons versus electrons. On the other hand, an atom is the smallest part of an element composed of electrons, protons, and the nucleus. So, ion-atoms with the same number of protons but a different number of electrons. Its not the easiest thing to study so you should complete your projects day by day from the day it was given.


Is a molecule part of a atom?

no an atom is a part of a molecule.


The part of the atom that accounts for electricity is the?

The electron is the part of the atom that accounts for electricity.


Do molecules have ions?

An atom is the smallest particle of a chemical element that retains its chemical properties. A molecule is the smallest amount of a substance that consists of a number of atoms of the same or of different elements.


What is the inner part of atom?

the nucleus of an atom


What is the part of the atom that makes up the mass of the atom?

Is a quark a part of the atom?

A quark is what makes up the nuetrons and protons of an atom. So yes, it could be counted as part of an atom.
