ytterbium - atomic number 70, so 70protons and 70 electrons, if neutral.
The number of neutrons may vary according to the isotope. Find its nucleon number and subtract 70 from it.
Commonest isotope Yb-174 has 104 neutrons.

Protons and electrons -- atomic number
Neutrons -- atomic weight minus atomic number
Your periodic table is your friend.
And by the way, the number of neutrons is different for different isotopes.
