Unstable isotopes occur when the strong force is unable to overcome the <span> <span>electrostatic force.</span></span><span>
There are no stable isotopes in the elements at the upper end of the periodic table, which clearly demonstrates the limit of the ability of the nuclear binding energy or the residual strong force, to overcome the electrostatic repulsion of all those protons in the nucleus.

Explanation:
so, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. electronegativity increases as you move from left to right across a period on the periodic table.
A plant growing into a shrub is an example of a chemical change because once the plant is in its shrub form you can't revert it back.
The answer is Heyyy friend in know because I took the test
Answer:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
Explanation:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
Methane + oxygen → carbon dioxide + Water.
The balanced equation above shows the combustion of methane, CH4 in oxygen, O2 to yield carbon dioxide, CO2 and steam, H2O.
The mole ratio of combustion are as follows:
1 mole of CH4 burns in 2 moles of oxygen to produce 1 mole of CO2 and 2 moles of H2O and a lot of heat.
