Atomic mass of the parent element =247,
atomic number of the parent element = 95
In the process of β-decay electron leaves the nucleus, so instead of one neutron we get one proton.
Mass of proton≈mass of neutron,
so atomic mass will not change.
Charge of proton =+1, and charge of neutron = 0.
So, we will get atomic number increased by one.
New element (daughter) will have
atomic mass = 247,
and atomic number= 95+1=96
Number 95 - Am (parent),
number 96 - Cm(daughter),
So, from Am-247 we will get Cm-247.
Answer:
Relating to, measured from, or as if observed from the earth's center.
Answer:
The answer to your question is: The mass number will be 4 units lower.
Explanation:
Alpha particles are Helium atoms, which have a mass number of 4 and atomic number of 2.
When an alpha particle is released, the original atom loses 2 protons and and 2 neutrons an we can see in the example.
²²⁶ ₈₈ Ra ⇒ ²²² ₈₆ Rn + ⁴₂ He
Cathode Ray experiment to figure out electrons exist -> atoms can be broken up into subatomic particles
<span>An aqueous solution is produced when a solute dissolves in water. The biggest responsible is the water that is the solvent of substances in smaller proportion as some ions of K +, Na +, Cl -, forming true solutions. Occurs when a solute dissolves in the water solvent, the separation between the substances is atomic, molecular or ionic, depending on the solution.</span>
