The atomic number of manganese is 25; its mass number is 55.
Anuta_ua [19.1K]

Answer:

c) 30

Explanation:

In an atom , the relation between the subatomic particles of the atom are given as follows -

For a neutral atom ,

Atomic number = number of protons = number of electrons ,

Mass number = number of protons + number of neutrons,

Hence , from the given information of the question,

Atomic number of Manganese = 25 ,

mass number of Manganese = 55 ,

Now, to calculate the number of neutrons , the above relation can be used -

Mass number = number of protons + number of neutrons,

Rearranging ,

number of neutrons = Mass number - number of protons

substituting the respective values ,

number of neutrons = 55 - 25 = 30 .

Which statements describe surface waves? Check all that apply.
neonofarm [45]

Answer:

The correct answers are "They travel slower than P waves", "They result in much ground motion" and " They are produced by P and S waves".

Explanation:

A surface wave can travel through the existing interface between Earth and air, as well as between Earth and water. A clear example of this type of waves are Love and Rayleigh waves. They travel slower than primary waves, produce large movements in the ground and are produced by primary and secondary waves.

Have a nice day!
