Answer:

The correct option is;

A) 1 to 1.

Explanation:

A stab;e nuclei requires the presence of a neutron to accommodate the the protons repulsion forces within the nucleus. An increase in the number of protons should be accompanied by an even more instantaneous increase in the number of neutrons to balance the forces in the nucleus. If there is an excess of neutrons or a deficit in protons a state of unbalance exists in the nucleus, which results to nuclear instability.

Therefore, the ratio of neutrons to protons is an appropriate way in foretelling nuclear stability and a stable nuclei is known to have a proton to neutron ratio of 1:1 and the number of protons and neutrons in the stable nuclei are usually even numbers.

An atom had an average atomic mass of about 63.5 amu. What is the chemical symbol for the atom?
Virty [35]

An atom has an average atomic mass of 63.5amu. 1 amu is equal to 1 gram per mole. So 63.5 amu is equal to 63.5 grams per mile or 63.5 g/mol. So the answer is Cu or Copper. Hope this helps. If it does, please mark as Brainliest.

Fossil fuel combustion increases the acidity of rain because the sulfur dioxide is produced.

Because of fuel combustion,  sulfur dioxide goes up into the atmosphere as the hot gases rise, than it reacts with water and oxygen in the air and form sulfuric <span>acid:

Identify the quantum numbers for the electron gained when an F2 ion becomes an F3 ion
zhuklara [117]

Answer: n= 3, l= 0 , m= 0 and s=[/tex]\frac{-1}{2}[/tex]

Explanation:

Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic quantum number :  It describes the orientation of the orbital. It is represented as 'm'. The value of m ranges from -l to +l.

Spin quantum number:  It describes the spin of the electron. It is represented as 's'. The value of s can be +1/2 or -1/2

F^{2-}:11: 1s^22s^22p^63s^1

F^{3-}:12:1s^22s^22p^63s^2

Thus electron enters 3s orbital , thus n= 3, l= 0 , m= 0 and s=[/tex]\frac{-1}{2}[/tex]
