When electrons are lost from an atom what type of ions are formed?

When electrons are lost from an atom, positively charged ions are formed. These ions are called cations.


Are atoms have lost electrons is called?

Atoms that have lost electrons are positive ions, and are called cations.


What are Atoms that carry an electrical charge called because they have gained or lost electrons?

Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.


What is formed if electrons are gained or lost?

An ionic bond between the ions (formed from the atoms).


An atom or a molecule that has gained or lost one or more electrons is called?

When an atom gains or loses electrons, it is trying establish a more stable situation in which it has a full valence shell. An atom that has gained or lost valence electrons is called an ion. When a positive ion and a negative ion can bond due to their opposite charges. This is called an ionic bond.


What Is a atom that grain or lost atom?

An atom that gains or loses electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.


Do ions have more electrons than the atoms from which they were formed?

of course, ions are formed by loosing (cations) or gaining (anions) electrons. anions have more electrons than the atom from which it is formed.


When metals lose electrons what do they form?

Metals lose electrons and form cations to get a full octet.


What is the difference between ion nd atom?

An ion is certain type of atom. Ions are atoms that have lost or gained electrons (often to have 8 valence electrons in the s and p orbitals).


An atom differs in electric charge from what?

An atom differs in electric charge from ions because atoms are electrically neutral, containing equal numbers of protons and electrons. Ions are charged particles resulting from atoms that have gained or lost electrons, creating an imbalance in the number of protons and electrons.


Are ions charged and isotopes are not?

An ion is an atom with gained electrons (anion) or which losses electrons (cation). An isotope of an element is an atom with a different number of neutrons but with the same number of protons and electrons. As any other atoms the atom of an isotope can gain or loss electrons.


What is an ion that has lost or gained electrons called?

An atom that has gained or lost electrons is called an ion. An atom that has gained one or more electrons becomes a negatively charged ion called an anion. An atom that has lost one or more electrons becomes a positively charged ion called a cation.
