Answer:
D They have the same properties.
Explanation:
The same no. of isotopes doesnot describes because isotopes have same symbol but didderent atomic mass.

Explosives are chemicals that have very fast burn rates at different degree.
First the Dynamite:
-The dynamite is an explosive that made from nitroglycerin, and it is a type of the explosive that has a fast burning rate and makes it very strong explosive. Physical shock can make the dynamite to explode and makes it highly dangerous.
-But the fireworks are a class of low explosive, the stuff that used in it is black powder.Because this explosive has a slow burn rate than dynamite that makes it less dangerous and safer than dynamite explosives
-SO although the dynamite and the fireworks are both explosives they have different burn rates which make them totally different in safeness.
1. The atomic number deceases by one and the atomic mass is unchanged - β⁺/positron emission. In this a proton is converted to a neutron, hence no net change in mass. Since a proton is converted to neutron, the daughter nuclide's proton number /atomic number decreases by 1. Then atomic number decreases by 1 and no change in mass.
2.the atomic number decreases by two, and the atomic mass decreases by four - alpha decay / ⁴₂α. alpha particles have 2 neutrons and 2 protons. Since 2 protons and 2 neutrons are emitted, the mass of the nuclide decreases by 4. Since 2 protons have been emitted, this results in atomic number decreasing by 2.
3.<span>the atomic number increases by one, and the atomic mass remains unchanged. - </span>β⁻ beta decay. In this type of decay - beta decay , a neutron is converted to a proton, therefore no net change in mass. Since a proton is formed, atomic number increases by 1. Therefore atomic number increases by 1 and no change in mass.
