yes it is true, they are the outermost electrons and sometimes get "stolen" by other elements creating an ion
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
Valence electrons are those that are in the outermost shell of the atom.
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.
The valence electrons are the outermost electrons, i.e. those that reside in the outermost energy level.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determining an element's reactivity.
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
The electrons farthest away from the nucleus are the valence electrons of an atom.
Valence electrons are those in the outermost shell of the atom.
A calcium atom has two valence electrons.
the electrons in the outermost shell of an atom are considered to be the valence electrons.
