Except for elements 1 and 2, all elements are stable with how many electrons in their outermost (valence) level?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
one valence electron
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
8
Boron has 3 valence electrons.Boron has 3 valence electrons.
The element chlorine has seven electrons in its valence shell.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
There is just one valance electron in the element potassium.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Lawrencium is a trivalent chemical element.
