Silicon (Si) has an atomic number of 14, meaning it has 4 valence electrons in its outer shell (the 3s and 3p orbitals). In the case of the Si 2- ion, it gains two additional electrons, bringing the total number of valence electrons to 6. Since the additional electrons occupy the 3p orbital, Si 2- has 4 valence s electrons and 2 additional p electrons. Therefore, Si 2- possesses 2 valence p electrons.

How many valence orbitals contain electrons in a neutral Si atom?
A neutral Si atom has 3 valence electrons, which reside in the 3rd energy level valence shell. Therefore, there are 3 valence orbitals in a neutral Si atom.
How many valence electrons are in SiCl3Br?
To determine the number of valence electrons in SiCl3Br, we need to account for the valence electrons of each atom in the molecule. Silicon (Si) has 4 valence electrons, each chlorine (Cl) atom has 7 valence electrons, and bromine (Br) has 7 valence electrons. Therefore, the total is 4 (Si) + 3 × 7 (Cl) + 7 (Br) = 4 + 21 + 7 = 32 valence electrons.
How many unpaired electrons does Si have?
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.
How many valence electrons does HSiN have?
To determine the number of valence electrons in HSiN, we can add the valence electrons from each atom: hydrogen (H) has 1, silicon (Si) has 4, and nitrogen (N) has 5. Therefore, HSiN has a total of 1 + 4 + 5 = 10 valence electrons.

What don you notice about the number of valence electrons as you move from left to right across a row or the period in the periodic table na-mg-al-si-p-s-ci-ar?
The number of valence electrons increases by one as you move from left to right across a period in the periodic table. Sodium (Na) has 1 valence electron, magnesium (Mg) has 2 valence electrons, aluminum (Al) has 3 valence electrons, silicon (Si) has 4 valence electrons, phosphorus (P) has 5 valence electrons, sulfur (S) has 6 valence electrons, chlorine (Cl) has 7 valence electrons, and argon (Ar) has 8 valence electrons.
Which electrons are responsible for current in a material?
The conduction band electrons. These are valence electrons that become delocalized in conductors and form an "electron gas" that fills the bulk of the conductor and can flow as a fluid in response to electric fields applied across the conductor.
