the answer to your question is easy, 2nd row of the periodic table so 2nd energy level and it has 3 valence electrons for a total of 5 electrons (2 in the first, 3 in the second) hope that helped your problem

∙ 14y agoBeing in Group Thirteen (III), Boron's outermost shell of electrons is comprised of 3 electrons. It's overall electron configuration is 2,3. This is paragraph contains the method with which to quickly determine an elements valence count- Save for Helium in group 18 (VII,0) which only has two valence electrons, those being its only electrons, the group number determines the valence electron count. The alkali metals all have 1 valence electron, and they are group one. Group 2, the alkali earths, all have 2 valence electrons, and so on. Another slight exception, this standard method is not used effectively to find the valence configuration of the transition metals. Thus, the D electron count is used. This process may be too technical to present, nor do I have the appropriate qualifications to explain accurately.

An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
What means outer energy level?
Valence electron
Can an electron in the outer energy level be called a valence electron?
Yes, it is correct.
What is an electron in the outermost energy level of an atom?
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.the valence electrons
What liquid non metal has the same energy level of calcium?
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
Valence electron are found in what energy level?
Valence electrons are the electrons in the outermost energy level.
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
What means outer energy level?
Valence electron
What are electron in the outer energy level called?
Valence electrons.
What is an electron in an atoms outer most energy level?
The electrons on the outtermost energy level of an atom is called a valence electron.
What is the name of the electron located in the outer most energy level?
The Valence electron
Can an electron in the outer energy level be called a valence electron?
Yes, it is correct.
What are the electron on the outermost energy level?
These are called valence electrons.
Are periods valence electrons or electron shell?
The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.
How many additional valence electrons does chlorine need to have a full valence shell?
11 electrons makes the third energy level complete. One
What term is used for the electron in the outermost shell or energy level?
These are the valence electrons.
What is an electron in the outermost energy level of an atom?
