Nitrogen (n) atomic number = atomic mass = number of protons = number of neutrons = number of electrons = number of electrons in the valence shell:

Nitrogen, Periodic abbreviation= N
Atomic Number: 7, as it has 7 protons
Atomic Mass: 14.007, so around 7 protons and 7 neutrons depending on isotope type
# Protons: 7
# Neutrons: 7
# Electrons: 7, usually, but not always, equal to # of Protons
Valence Electrons: 5, as with 7 electrons total, 2 would fill the first valence shell, leaving 5 in the valence, or outermost, shell.

Hi. where is the graph?

Ethene molecular fórmula= c2h4molecular weight = 29.046g/molhope it : )
