Question:

Why is it possible to have a purely covalent bond but not a purely ionic bond?

Inactive
Sophia F.
Answer:

A purely covalent bond exists in diatomic molecules because the atoms, being identical, are equally attracted to the shared electrons. In ionic bonds the electrons being transferred are never completely released from one atom to another. Instead, they tend to spend more of their time around the atom with the stronger attraction.

Answer:

In covalent bonds electrons are shared between atoms. In ionic bonds, on the other hand, electrons are transferred from one atom to another. Covalent = co... couple... two (or more) joined together. Ionic = ion... the transfer of elections form ions.

Question:

Do our bodies still consume energy even when we are completely at rest?

Answer:

Yes. Apart from what we think of as typical energy requiring processes, such as talking and working, there are a number of involuntary processes constantly taking place in our bodies in order to keep us alive. These also require energy and they include things like breathing and maintaining a heart beat.
