Use lewis dot symbols to show the sharing of electrons between a nitrogen atom and fluorine atoms to form a molecule in which each atom has an octet of electrons.

Explanation:

Lewis dot structure is the representation of the valence electrons around the atom of an element. it also shows the number of unpaired electrons present in a molecule.

Nitrogen has atomic number of 7 and electronic configuration is given as:

Fluorine has atomic number of 9 and electronic configuration is given as:

Since fluorine is highly electronegative atom.will attract electrons of nitrogen towards itself.So in Lewis dot structure the fluorine atom will present around single nitrogen atom.

The Lewis structure is given in an image attached.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
