Answer:
To break down the nucleus of an atom
Explanation:
Remember to change from one element to another, is necessary to add protons, neutrons and electrons,in most of the cases.
The take an electron from an atom you need certain energy, but they are in the outside part of the atom so is not as much energy as the one is necessary to take one neutron or proton from the inside part of an atom.
In this way, is a must to have a combination of pressure and heat to destabilize an atom and take some of this subatomic particles.
A simple circuit consists of a battery to provide power, wires to carry the electrical power, and
load that uses the electrical power for example a light globe

Answer:
isotope 2
Explanation:
it has the highest percentage abundance
Answer:
The average atomic weight = 121.7598 amu
Explanation:
The average atomic weight of natural occurring antimony can be calculated as follows :
To calculate the average atomic mass the percentage abundance must be converted to decimal.
121 Sb has a percentage abundance of 57.21%, the decimal format will be
57.21/100 = 0.5721 . The value is the fractional abundance of 121 Sb .
123 Sb has a percentage abundance of 42.79%, the decimal format will be
42.79/100 = 0.4279. The value is the fractional abundance of 123 Sb .
Next step is multiplying the fractional abundance to it masses
121 Sb = 0.5721 × 120.904 = 69.169178400
123 Sb = 0.4279 × 122.904 = 52.590621600
The final step is adding the value to get the average atomic weight.
69.169178400 + 52.590621600 = 121.7598 amu
