That is false
Comment if you need an explanation why
If you add the amount of protons with the amount of neutrons, you get the atomic mass. Sodium has 11 protons, and 12 neutrons. 11+12=23
There is a 50% probability that the flowers of a plant with pink flowers parents will have pink flowers due to incomplete dominance.
The genotypes and phenotypes that we will employ to address this issue are as follows:
RR - Red
RW - Pink
WW - White
They would have the RW genotype as the first parent plant is pink. They would have the WW genotype because the other parent is white. When the Pink flower parents are crossed, the children that might be expected from this cross
RW x RW
The progeny will be : 1 RR (Red), 2 RW (Pink) and 1 WW (White)
This shows that there is a 50% probability that the progeny will have the RW genotype and thus the pink phenotype. Additionally, we can observe that there is a 25% likelihood that the progeny will have the WW and RR genotype and the white and Red phenotype.

Answer:
A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule
Explanation:
Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.
However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.
This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.

When the outer electron shell is full in an element, this creates a Noble gas.
<u>Explanation</u>:
Noble gases are the elements that belong to group 18 in the periodic table. Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.
There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.
