Scandium protons and electrons
WebThe electron configuration for scandium is: $$\ce{1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1}$$ The $\ce{4s}$ and $\ce{3d}$ orbitals are relatively close in energy, so there are a few anomalies in the order of filling. A fair question might be, why isn't the scandium electron configuration $\ce{[Ar] 3d^3 4s^0}$. WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts.

Webanswer choices. An Indium (In) atom contains 115 protons inside the nucleus, and 49 neutrons outside the nucleus. A Scandium (Sc) atom contains 45 electrons outside the nucleus, and 21 neutrons inside the nucleus. An Aluminum (Al) atom contains 27 electrons and 27 protons inside the nucleus. Web(a) The tendency of an atom to lose electrons increases on moving down in a group of the periodic table. As we go down in group 1, one more electron shell is added at every stage and the size of the atom increases. The valence electrons become more and more away from the nucleus and hold of the nucleus on valence electrons decreases.
