Electrons are transferred from one atom to another describes ionic bonding.

Option D

<u>Explanation</u>:

Ionic bonding requires at least one acceptor and one donor. ''Ionic bond'' is the movement of ''valence electrons'' between atoms. It gives two oppositely charged ions after taking place. The metal loses electrons and form a positive cation, and non metals gains electrons to become negative cations. Thus electron donor is a metal, and electron acceptor is usually a non metal. Thus, it is evident that in ionic bonding electrons are transferred between atoms.

D. Ionic bonding is when electrons are transferred. When they're shared, it is covalent. In order to take an electron from a full valence electeon shell, you would need a massive amount of energy.

A person weighing 0.9 kN rides in an elevator that has a downward acceleration of 1.9 m/s^2. The acceleration of gravity is 9.8

Keith_Richards [23]

Answer:

The magnitude of the force is 0.7255kN

Explanation:

The elevator floor acts on the person with a force that is due to the gravitational acceleration less the downward acceleration of the elevator:

(force of floor F) = (mass of person m) x [ (grav. acceleration g) - (elevator acceleration a) ]

in other words, considering the elevator floor as a reference frame in the Earth's gravitational field, the person's weight decreases due to the downward acceleration, as follows:

$F = m\cdot(g-a)$
