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.
There are 16 dots in the Lewis Dot Structure of H2Se. Each hydrogen atom contributes 1 dot and selenium contributes 6 dots.
In a Lewis structure, the valence electrons of an atom are represented as dots. Valence electrons are the electrons in the outermost energy level of an atom and are involved in chemical bonding. These electrons are important in determining the chemical properties of an element.
The dot structure for IO4 starts with the I atom in the center. from this, there are three doubly bonded O atoms and one singly bonded O atom. The O atom has three pair of dots and the others have two pair of dots. The structure is then bracketed and noted with a 1- superscript.

In a Lewis dot structure for an oxygen atom, there should be six dots. Lone pairs of electrons are represented by dots around the symbol for the atom. Oxygen has six valence electrons, so it will have a total of six dots in its Lewis dot structure.
The Lewis symbol for a nitrogen atom is N with five dots around it, representing its five valence electrons. The Lewis symbol for a chlorine atom is Cl with seven dots surrounding it, representing its seven valence electrons.
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.
okay ay man its Benny J jammin. havent got a clue . help me out

There is one dot around the Na in the Lewis symbol for a neutral atom of Sodium.

Lewis dots are concerned with electrons in the outer most shell of an atom. This means that no matter how many electrons an element contains, Lewis dots will never number higher than eight.
The correct Lewis Structure for the oxygen atom will be an 'O' with two dots above and below, with one dot on the left and on the right sides.
