Answer:

The electric force is conservative.

Since

ΔK = −ΔU,

Kf − Ki =Ui −Uf.

We have,

Kf = 0

Ui = 0.

Thus Ki =Uf.

<u>so ,at 10 fm Uf = (2×10)−12 J.</u>

An atom with an atomic number of 10 and a mass number of 24 would have ________.
Anastaziya [24]

An atom with an atomic number of 10 and a mass number of 24 would have 14 neutrons.

<h3>What is atomic number and mass number?</h3>

The term atomic number, conventionally denoted by the symbol Z.

Atomic number indicates the number of protons present in the nucleus of an atom, which is also equal to the number of electrons in an uncharged atom.

The mass number of a given atom is defined by the number of protons and neutrons present in the nucleus. In simple,

Protons + Neutrons = Mass Number

8. Based on the formula, predict whether each of the following compounds is primarily ionic or primarily covalent. a. sodium iod
Lina20 [59]

primarily ionic  include = sodium iodide( NaI) ,   calcium chloride  ( CaCl2)


primarily covalent    include  - Ammonia (NH3) , Methane ( CH4)  and  

                                                   Glucose  (C6H12O6)


Explanation

ionic  bond  is formed  when  there is complete transfer of electron between atoms. It occur  between metal  which  donate electrons and  a  non  metal which accept  electrons.

 for  example  in  formation  of CaCl2,   ca  donate  2 electron to 2  Cl atom, while  2 Cl atom accept the 2  electrons  to form ionic bond.

 Covalent bond  is formed  when two or  more  non  metal  form bond by sharing  electrons pairs.

For  example in NH3   3 pairs of electron are shared.  to form covalent bond.
