How is electron movement related to the bonding in sodium chloride? A) The atomic orbitals overlap and share electrons causing an ionic bond to form. B) Electrostatic sharing of electrons between atoms allows covalent bond formation. C) Electrons exchange creating ions to form an ionic bond by electrostatic attraction. D) Orbital overlap occurs between the atoms to exchange electrons to form the covalent bond.

Answers

Answer: Option (C) is the correct answer.

Explanation:

Sodium has atomic number 11 and its electronic distribution is 2, 8, 1. Whereas chlorine has atomic number 17 and its electronic configuration is 2, 8, 7.

Therefore, we can see that sodium has one extra electron and chlorine has deficiency of one electron.

So, in order to complete their octet sodium will give its one valence electron to the chlorine atom. Hence, there is exchange of electrons and thus it will result in the formation of ionic bond.

Thus, we can conclude that in sodium chloride electron movement is related to the bonding as electrons exchange creating ions to form an ionic bond by electrostatic attraction.

Answer:

so your wondering how electricity goes from power plants to your home? well, here's why.The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. It travels through distribution lines to your neighborhood.
Electricity goes from power plants to our homes through a step-down transformer. This helps the voltage to be lowered because electricity has to have high amounts of voltage to travel. So once it’s been lowered, electricity gets transferred to smaller wires that connect to our outlets.

Which statement describes between a cup if cold water and a cup of boiling water

Answers

The thermal energy keeps these two changing their temperature over time. 

The surrounding temperature (environment) clearly effects the cold water AND the boiling water. 

Eventually, both would reach an equilibrium in temperature. 

which is the of these their statements correctly describes a key difference between aerobic activity and anaerobic activity

Answers

aerobic uses oxygen to liberate heat while anaerobic is in the absence of oxygen.
