"An atom or ion has 43 neutrons , 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number and charge for this atom or ion."

1. Mass number = 79

2. No charge

Explanation:

From the question given, we obtained the following data:

Neutron = 43

Proton = 36

Electron = 36

Mass number = proton + Neutron

Mass number = 43 + 36

Mass number = 79

Atomic number = proton number = 36

Therefore the element is Krypton (Kr).

The element has no charge since the proton number and electron are the same. its outer shell is completely filled being a member of the noble gas family(i.e group 0). From the calculations made above this element is simply an isotope of krypton because krypton has a mass number of 84 normally. Since the mass number(79) obtained above is different from this(84), it therefore means they have a different neutron number which is the basis for isotopy.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
