There should be 3 dots in the electron dot diagram of a boron (B) atom, as boron has 3 electrons. Each dot represents one valence electron.
there are 6 valence electrons in the outermost energy levei
An electron dot diagram, also known as Lewis dot diagram, uses dots to represent the valence electrons of an atom.
The Lewis dot diagram for SiS2 would show Silicon (Si) at the center with one sulfur (S) atom on each side. Each sulfur atom would have six dots around it to represent its valence electrons, while silicon would have four dots around it.
In the electron dot diagram for a sulfur ion, there would be eight dots represented. This is because sulfur typically forms an ion with a 2- charge, so it needs two more electrons to achieve a full outer shell of eight electrons.
Sulfur is in group XVI (or 6A) and so has 6 valence electrons. The electron dot diagram for S would thus have to show (b) six dots.
In an electron dot diagram, the number of dots surrounding an atom represents its valence electrons. Each pair of dots can form a bond, meaning that the number of bonding pairs (dots that are shared between atoms) indicates how many bonds the atom can form. For example, if an atom has four valence electrons, it can form up to four covalent bonds by sharing those electrons. Thus, the arrangement of dots directly relates to the bonding capacity of the atom.
