Valance electron
When an atom is no longer neutral and has gained or lost electrons, it is called an ion. An atom that has gained electrons will have a negative charge (an anion), while an atom that has lost electrons will have a positive charge (a cation).
an ion is an atom thats no longer neutral because it gained or has lost electrons.
An atom with no electric charge will be called a neutral atom. In a neutral atom, there is a balance of charges, and the number of protons will be equal to the number of electrons. It's really that simple. Compare this to atoms that have an imbalance of charges. These atoms are called ions.
An S2- ion has gained two electrons, giving it a 2- charge, while a neutral sulfur atom has an equal number of protons and electrons. This means that the S2- ion has two more electrons than a neutral sulfur atom.
Such an atom would be neutral - no electric charge.
An atom that is no longer neutral has gained or lost electrons, resulting in a net positive or negative charge. A positively charged atom is called a cation, while a negatively charged atom is called an anion. These charged atoms are called ions.
An atom that is not neutral because it has gained or lost electrons is called an ion. If it gains electrons, it becomes a negatively charged ion, or anion; if it loses electrons, it becomes a positively charged ion, or cation. This change in charge occurs due to the imbalance between the number of protons and electrons in the atom.
An "Ion" is an atom that has gained or lost an electron and is therefore no longer electrically neutral.
There are 17 electrons i a neutral atom of chlorine.
A neutral atom has an equal number of protons and electrons, resulting in no overall charge. An ionized atom has gained or lost electrons, creating a positive or negative charge. This difference in charge affects the atom's chemical behavior and reactivity.
A neutral atom is an atom with an equal number of electrons and protons without any additional energy. An excited atom has electrons that have absorbed energy and moved up to another layer. Ions are atoms that have a different number of electrons from the neutral atom.
Neon has ten electrons and as a Nobel gas is generally neutral
