Neutrons

How many protons, neutrons, electrons, and valence electrons are in each of the above elements?

Sodium: Protons=11, Neutrons=23-11=12, Electrons=11, Valence Electrons=1Carbon: Protons=6, Neutrons=12-6=6, Electrons=6, Valence Electrons=4

1)Protons are positively charged particles.2)Protons are found in the nucleus of an atom, along with neutrons.3)On the periodic table, the atomic number (usually displayed at the top of the square) is equal to the number of protons.4)Protons are shown with a + sign.

1)Neutrons are particles with no charge.2)Neutrons are found in the nucleus of an atom, along with protons.3)The number of neutrons is equal to the mass number (usually displayed at the bottom of the square on the periodic table) minus the atomic number.4)Neutrons can be shown with an x, an N, or a 0.

Electrons

1)Electrons are negatively charged particles.2)Electrons are found in an area of the atom outside of the nucleus called the electron cloud.3)In a stable element, the number of electrons is equal to the number of protons.4)Electrons are shown with a - sign.5)Valence electrons are the number of electrons in the outermost layer of the electron cloud. The number of valence electrons are equal to the last digit in the element's group number.
