a neutral atom, has 62
Samarium is an element in the periodic table, atomic number 62, chemical symbol Sm.
The noble gas notation for samarium is [Xe] 6s2 4f6.
A neutral atom of samarium has 2 valence electrons. If you write out the electron configuration of samarium, you will find that all of the shells up to four are full. When you get to shell five you have two electrons left. These are the two valence electrons. You can always find valence electrons by the electron configuration.
The Element Neon has 10 protons and 10 electrons.
8 electrons
2 valance electrons
Because the atomic number is 62, the element Samarium has 62 electrons and 62 protons. Since the number of neutrons is calculated by subtracting the atomic number from the atomic mass, and Samarium's atomic mass is 150, it has 88 neutrons.
Samarium is an element in the periodic table, atomic number 62, chemical symbol Sm.
The Dr. Seuss phrase "Oh the Thinks You Can Think!" is derived from the periodic table element "thinks" which corresponds to element 111, Roentgenium.
