The correct Lewis structure for a Group 18 atom has?

Answer 1

The correct Lewis structure for a Group 18 atom, also known as a noble gas, would show the atom with a full outer shell of electrons. This would typically be represented by a symbol of the noble gas surrounded by eight dots, representing the eight valence electrons in the outer shell. These atoms are considered stable and do not readily form chemical bonds due to their full outer electron configuration.

Answer 2

With the exception of helium, the group 18 atoms will have as their Lewis structure the elemental symbol surrounded by 4 pairs of electrons, each electron represented by a dot. These are the noble gases, and they are, for the most part, chemically inert, which means they do not typically react with any other elements. Helium will only have one pair of electrons shown.

Answer 3

The same as for 16-Oxygen!I think you may have been thrown a trick question. Isotopes have NO effect on proton or electron numbers, only neutrons.

Just draw the same Lewis structure you would for any oxygen (6 valance electrons).

Answer 4

The correct Lewis structure for a Group 18 atom, such as helium, neon, or argon, would just be the elemental symbol surrounded by 8 valence electrons (duet for helium) as these elements have a full outer shell of electrons.

Answer 5

The correct Lewis structure for a Group 18 atom will show a central atom that is a noble gas and it will be surrounded by 4 lone pairs.
