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
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
Aluminum has three unpaired electrons.
Germanium has 4 unpaired electrons.
6 unpaired electrons
Phosphorus has three unpaired electrons in its ground state.
Nickel has two unpaired electrons.
