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.
Such an atom would be neutral - no electric charge.
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).
A neutral atom must contain an equal number of electrons because it is a neutral atom.
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.
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.
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.
Valance electron
an ion is an atom thats no longer neutral because it gained or has lost electrons.
Such an atom would be neutral - no electric charge.
5 electrons because no. of protons= no. of electrons
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which represents the number of protons and electrons in a neutral atom.
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).
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which corresponds to the number of electrons it has when it is electrically neutral.
The neutral atom of cadmium has 48 electrons.
A neutral atom of uranium has 92 electrons. This is because the number of electrons is equal to the number of protons in the nucleus of an atom, and an atom is neutral when the number of electrons is equal to the number of protons. Uranium has an atomic number of 92, which corresponds to the number of protons and electrons in a neutral atom of uranium.
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.
There are 17 electrons i a neutral atom of chlorine.
