Which description refers to fog?
Aneli [31]

Answer:

The correct option is;

Is found near bodies of water

Explanation:

Fog forms as an aerosol which is visible to the eye that normally consists of tiny condensed water vapor droplets or crystals of ice that is formed when air that is warm comes in contact with cool air close to the Earth's surface. Fog can be taken as a stratus like cloud that lies close to the Earth's surface and it normally forms due to the presence of water bodies that are nearby, the topography of the area or the conditions of the wind.

58-Ni has an atomic number of 28 which are the protons and a mass number of 58. Since the mass number is 58 this is the protons
Kaylis [27]

Answer:

Explanation: Nickel is element number 28 on the period table with a mass number 58 or 60, it exist in two forms and the phenomenon is known as isotopy

Definition of Isotopy is simply a phenomenon whereby elements exist in various forms that have the exact same chemical properties but different atomic mass.

58-Ni has atomic number 28 because that's the number o the element on the periodic table. Proton number is the same as atomic number and same as electron number for a neutral element or element without charge.

Mass number = Proton number (P) + Neutron number (N)

58 = 28 + N

N= 58-28

N= 30

58-Ni has 28 has the atomic number, proton number and electron number because it is a neutral atom but the neutron is 30 as shown in the calculation above.

60-NI+2 has a contrasting figure because the element has a charge of +2

Mass number= Proton + Neutron

60 = 28 + N

N= 60 - 28

N= 32

Electron = Proton - Charge

                 28 - (+2)

                  28 - 2

Electron = 26

The number of electron in 60-Ni +2 differs from 58-Ni because of the number of charge

Electron number differs from proton number in any element with a charge.
