The answer is: Survival of the form that will leave the most copies of itself in successive generations.
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory.
This is example of natural selection and adaptation.
Genetic variation is important to the population's ability to survive in different situations that affect natural selection.
The environment is constantly changing and different alleles are favored.
Molecular orbital energy is the energy associated with each electron in an atom or molecule.
It is expressed in electron volts (eV) and is determined by the electron's position in the atom or molecule. The molecular orbital energy diagram and fill-in the electrons are given here in each case, the number of valence electrons in the species is determined first; this is followed by the valence molecular orbital diagram for each species.

Answer:
Intensive properties do not depend on the quantity of matter. Examples include density, state of matter, and temperature. Extensive properties do depend on sample size. Examples include volume, mass, and size.

Answer:
Radon is the heaviest Noble Gas
Explanation:
This statement is very easy to be solved. As we know that Noble Gases are group of Elements which have complete valence shell and are stable elements and don't react easily and hence, are found in mono-atomic form in nature. These elements can be found on the extreme right of the periodic table in group 8 or group 18. Following are the Noble elements,
(i) Helium
(ii) Neon
(iii) Argon
(iv) Xenon
(v) Radon
Now,
In statement we are provided with only two noble gases i.e. Helium and Radon. Therefore, it is easy among them to finalize the heaviest one as Radon having atomic mass of 222.02 g/mol and atomic radii of 0.22 nm is much denser/heavier than Helium having atomic mass of 4.0 g/mol and atomic radii of 0.122 nm.
