The molecular structure of BECl is linear, with beryllium at the center and one chlorine atom on each side. In a Lewis structure, beryllium is represented with two valence electrons and each chlorine atom with seven valence electrons. The beryllium atom forms a bond with each chlorine atom, resulting in a total of two bonds and no lone pairs on beryllium.
they are the electrons in the outer shell of the atom(valence electrons)
Four valence electrons need to be accommodated in the Lewis structure for F2. Each fluorine atom contributes seven valence electrons, totaling to fourteen valence electrons in the molecule.
the dots are the number of electrons in an elements valance shell (last shell). if it has no dots, it means it has lended its electrons to another element to become stable like its nearest noble gas.
6 valence electrons need to be accommodated in the Lewis structure for OF2. This accounts for the oxygen atom's 6 valence electrons and the fluorine atom's 1 valence electron each.
These would be the elements in group 16. The elements in group 16 have six valence electrons. Those valence electrons are represented in a Lewis diagram by surrounding them with six dots. When drawing a diagram for an element with six valence electrons, there should be two pairs of dots (four total), and two separate 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.
Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.
It represents the number of valence electrons in the atom.

The correct Lewis structure for selenium (Se) would have 6 valence electrons represented by the symbol "Se" surrounded by 6 dots or lines (representing valence electrons), giving a total of 12 electrons in the structure.
5 electrons where two electrons are paired and three are unpaired
the dots are the number of electrons in an elements valance shell (last shell). if it has no dots, it means it has lended its electrons to another element to become stable like its nearest noble gas.
There are 20 valence electrons in the expanded valence structure of sulfur dioxide. This includes the electrons from the sulfur atom (6 valence electrons) and each oxygen atom (6 valence electrons each).
6 valence electrons need to be accommodated in the Lewis structure for OF2. This accounts for the oxygen atom's 6 valence electrons and the fluorine atom's 1 valence electron each.
