Answer:
d. usually neutral
Explanation:
The overall charge of an ionic compound is usually neutral.
There is no net charge on the compound formed by an ionic bond due to the electrical stability that is derived from this bond association.
In an ionic bond, a metal transfers some of its electrons to a non-metal. The metal is electropositive and the non-metal is electronegative.
Therefore, the result is that two ions are produced which attracts each other with an electrostatic force.
Answer: Find the answer in the explanation
Explanation:
Bohr postulated that :
1.) Electrons revolve in specific circular orbits around the nucleus and these orbits can be represented by the letters K, L, M, N.
2.) Electrons revolving in a particular orbit are in a stationary state. They can neither gain energy nor loose energy. 3.) But if an electron jumps from an higher orbit to a lower orbit it will emit energy in the form of radiations. Also if an electron jumps from lower orbit to a higher orbit it excites and absorbs energy in the form of radiations.
4.) Neil Bohr experimental findings about angular momentum of an electron shows more light on the stability of atom and the line spectrum of hydrogen atom
