What happens with the electrons when an atom froms a cation and an anion?
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
What happens to the structure of an atom to change the atom into an ion?
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
What happens when a atom forms an ion?
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric charge.
What happens when an atom loses one or more electrons and retains the same number of protons?
This atom become a positive ion (cation).
What happens when you have 3 electrons in an atom?
You have Lithium.
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 if a atom does not have anough electrons?
If an atom does not have enough electrons, it becomes positively charged and is referred to as a cation. This can occur when an atom loses one or more electrons during chemical reactions, leading to an imbalance between the number of protons (positive charge) and electrons (negative charge). As a result, the atom may seek to gain electrons from other atoms or molecules to achieve a more stable electronic configuration.
What happens when an atom has more electrons than can fit in one energy?
Answer this question… The extra electrons begin to fill the next energy level.
When an atom becomes a cation what happens to its of electrons and its overall radius When at atom becomes an anion what happens to its of electrons and its overall radius?
When an atom becomes a cation, it loses one or more electrons, resulting in a positive charge and a decrease in its overall radius due to reduced electron-electron repulsion. Conversely, when an atom becomes an anion, it gains one or more electrons, leading to a negative charge and an increase in its overall radius due to increased electron-electron repulsion.
What happens if atom loses electron?
When an atom loses electrons it becomes ionized and more positive a charge. Losing an electron can cause this atom to react with other atoms.
What causes an atom to be stable and unstable?
An atom is stable when its nucleus has a balanced ratio of protons and neutrons, and when its electrons are in filled energy levels. An atom is unstable when it has an imbalance of protons and neutrons in the nucleus, leading to radioactive decay in an attempt to reach a more stable configuration.
When an atom in a reactant gains electrons what happens to its oxidation number?
The oxidation number decreases because gaining electrons leads to a more negative charge, reducing the overall positive charge of the atom.
