What else can I help you with?
How many valence electron are needed for an atom to be stable?
It depends on the atom. List what element the atom is from.
What happens to the electron as it moves closer to the nucleus?
An electron moving towards the nucleus slows down and any energy it contains from a higher shelf is released.
What is the best representation of the electron in an atom?
Valence electrons are the electrons involved in chemical reactions.
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
What is the electron configuration for a neutral atom of beryllium?
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
How many valence electrons does an atom of potassium have?
4
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
What is likely to happen to an atom with one valence electron?
This atom lose an electron.
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.
How many valence electrons does a group 1A metal atom have?
they all have one valence electron.
What is the difference between a electron and a valence electron?
While electrons can be on any layer, a valence electron is an electron that is found in the outermost layer of an atom and that determines the atom's chemical properties.
How many valence electrons does serine have?
Serine has five valence electrons. It has three valence electrons from the oxygen atom and one valence electron each from the carbon and nitrogen atoms in its structure.
Is a valence electron the same thing as a electron?
Yes, but valence electrons are always in the outer electron shell of an atom.
What do the electrons in an electron dot structure represent?
It represents the number of valence electrons in the atom.
How many valence electrons does a hydrogen atom have?
A hydrogen atom has 1 valence electron.
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.
How can an atom that has five valence electron achieve a full set of valence electron?
An atom with five valence electrons can achieve a full set of eight valence electrons by either gaining three electrons (to reach a stable octet) or losing three electrons to have a stable arrangement. This would result in the atom forming an ionic bond, such as in the case of boron transferring three electrons to become the boride ion.
