a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.(:
Electrons in the outermost shell are valence electrons!
the electrons in the outermost shell of an atom are considered to be the valence electrons.
Lone-pair electrons, Bonded pairs of electrons
Valence electrons
8 electrons
Electrons charge is a negative
4 electrons, 2 valence electrons
Chlorine has 17 electrons. 7 of its electrons are valence electrons.
The electrons farthest away from the nucleus are the valence electrons of an atom.
A metalloid with 4 electrons, such as silicon, has 2 core electrons. In the case of silicon, the electron configuration is 1s² 2s² 2p², where the 1s² electrons are the core electrons, while the 2s² and 2p² electrons are considered valence electrons. Thus, it has 2 core electrons and 4 total electrons.
N(nitrogen) = 7 electrons 3O(three oxygen) = 3* 8 electrons = 24 electrons 7 electrons + 24 electrons = 31 electrons in NO3 ( nitrogen trioxide ) ==============================
These electrons are called valence electrons.
