An electron in the outermost energy level of an atom is called a valence electron.
(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)
These electrons determine the chemical reactivity of the atom.

An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
Can an electron in the outer energy level be called a valence electron?
Yes, an electron in the outermost energy level of an atom is called a valence electron. Valence electrons are involved in chemical bonding and determining the reactivity of an atom.
An atom with an incompletely filled outermost energy level is likely to be?
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.
Describe what happens to the outermost electron in a sodium atom when the atom is heated and made to give off a line spectrum?
When a sodium atom is heated and gives off a line spectrum, the outermost electron absorbs energy and gets excited to a higher energy level. As the electron returns to its original energy level, it releases this energy in the form of light, creating the characteristic line spectrum of sodium.
How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of a water molecule?
An oxygen atom has 6 electrons in its outermost energy level. In a water molecule, each hydrogen atom can share one electron with the oxygen atom, forming a covalent bond. This results in the oxygen atom having a total of 8 electrons in its outermost energy level.
An atom contains seven electrons in its outermost energy level the atom is what?
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
A - 1s22s22p63s1 B - 1s22s22p65s1 What is the difference between atom A and atom B?
The electron configurations provided represent the electron arrangement in the outermost energy level of the atoms. Atom A has a 3s1 electron configuration, indicating it is in the third energy level with one electron in the s orbital. Atom B, on the other hand, has a 5s1 electron configuration, indicating it is in the fifth energy level with one electron in the s orbital. Therefore, the main difference between atom A and atom B is the energy level in which their outermost electrons reside.
How many electrons are in a chloride ion's outermost energy level?
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
What electron would require the least amount of energy to remove from the atom of sulfur?
This is an electron situated on the outermost level.
What is an electron called in the outermost energy level?
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
Which electron in an atom are the valence electrons?
The valence electrons are the outermost electrons, i.e. those that reside in the outermost energy level.
Can an electron in the outer energy level be called a valence electron?
Yes, an electron in the outermost energy level of an atom is called a valence electron. Valence electrons are involved in chemical bonding and determining the reactivity of an atom.
An atom with an incompletely filled outermost energy level is likely to be?
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.
When is electron a valence electron?
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
Describe what happens to the outermost electron in a sodium atom when the atom is heated and made to give off a line spectrum?
When a sodium atom is heated and gives off a line spectrum, the outermost electron absorbs energy and gets excited to a higher energy level. As the electron returns to its original energy level, it releases this energy in the form of light, creating the characteristic line spectrum of sodium.
When is an electron a valence electron?
when it is on the very outside level away from the nucleusA valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.)It is an electron in the outermost shell of the atom.
