2 and 1 respectively
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.
There are no unpaired electrons in strontium.
Nickel has two unpaired electrons.
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
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.
A silicon atom has 4 valence electrons. These electrons are paired up in the 3s and 3p orbitals. Therefore, a silicon atom does not have any unpaired electrons.
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.
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.
There are no unpaired electrons in strontium.
three unpaired electrons
Aluminum has three unpaired electrons.
Germanium has 4 unpaired electrons.
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
6 unpaired electrons
Phosphorus has three unpaired electrons in its ground state.
Nickel has two unpaired electrons.
