Show a diagram of how ions are formed when a sodium atom comes into close
Firdavs [7]

Answer:

The diagram is attached below.

Explanation:

when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.

Both atoms bonded together through ionic bond.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.

A meteorologist observes a decrease in barometric pressure and predicts a chance of light to moderate precipitation. Which front
Dmitrij [34]

Answer:

Warm front

Explanation:

A warm front is the transition zone of the replacement of a cold air mass by a warm air mass. The pressure centers of warm fronts are usually low and the pressure read by a barometer will decrease due to an incoming warm front

The general direction of motion of warm fronts is from southwest to northeast with warmer and moist air behind the warm front than air into which the front flows. Therefore, warm fronts normally results in moderate precipitation or rainfall or snow.
