2.
An atom of yttrium (Y) has an electron configuration of 1s2,2s2,2p6,3s2,3p6,4s2,3d1, so it has one unpaired electron in the 'd' orbital.
Silicon has 0 unpaired electrons. It is a nonmetal with an electron configuration of [Ne]3s^23p^2, meaning it has 4 valence electrons that pair up in its orbital arrangement.
It has 14 electrons with an electron arrangement of 2,8,4
Regardless of the isotope, every silicon atom has 14 electrons.
There are six unpaired electrons in a sulfur atom (atomic number 16) because sulfur has six valence electrons in its outer shell.
Silicon has 0 unpaired electrons. It is in group 14 of the periodic table and has 4 valence electrons, which will form covalent bonds, leaving no unpaired electrons.
An atom of antimony in its ground state has 3 unpaired electrons.
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
