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.

How does an s2- ion differ from an electrically neutral sulfur atom?

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.

Number of electrons present in a neutral barium atom?

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 in no longer neutral it exists with a charge an atom that has a charge is called a?

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).


How many electrons are present in a neutral barium atom?

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.


How many electrons would a neutral atom of cadmium have?

The neutral atom of cadmium has 48 electrons.


Number of electrons in a neutral atom of uranium?

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 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.
