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.
There are62 protons in samarium, and each atom of samarium will have this many protons. THE PROTONS ARE THE BEST THING THAT U CAN ASK TO BE IN UR SCIENCE WORD BECAUSE IF U DO NOT HAVE THE RIGHT ANSWER U ARE GOING TO GET THE PRONTONS WRONG AND MRS.PARK
Samarium atoms have 62 protons in their nuclei. Use the link below to check facts and learn more.
Which set of numbers best describe s the value of each variable? the number of times (n) a cricket chirps; the outdoors temperature (T) in tenths of a degree
Samarium has 88 neutrons.
Depends on the isotope.
There are 58.
Shut up dude

56 protons.
The atomic number is the number of protons in an atom's nucleus.
76 of them.
17
That would depend on how many protons exist in the nucleus of the atom. An atom with 6 protons is a carbon atom; 7 protons is nitrogen, and 8 = oxygen.
21
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
There are 24 Protons in Chromium's nucleus.
Lawrencium has 103 protons in the atomic nucleus.
There are four protons in the nucleus of a beryllium atom.
there are 80 protons in the nucleus of an atom of mercury
Radon has 86 protons.
Californium has 98 protons.
56 protons.
Bohrium has 107 protons.
In atoms, their can be as many protons as neutrons.So the answer is yes.
The atomic number IS the number of protons in the atom's nucleus.
