Answer:
The elements in increasing order of atomic radius: oxygen, carbon, aluminum, potassium
Explanation:
The distance from the center of the nucleus to the outermost shell of the electron is known as the atomic radius of an element. The atomic radius decreases rightward along each period (row) of the table due to the increase in effective nuclear charge (the charge of the nucleus equal to the number of protons). Across a period, electrons are added to the same energy level and the increasing number of protons causes the nucleus to exert more pull on these electrons, which makes the atomic radius smaller. Atomic radius increases down each group (column) of the periodic table because of the addition of electrons to higher energy levels, which are further away from the nucleus and the pull of nucleus weakens. Another reason for the increase in atomic radius is the electron shielding effect, which is the reduction of the attractive force between a nucleus and its outer electrons due to the blocking effect of inner electrons
While moving from left to right in the second period, c
arbon comes before oxygen and so oxygen will have a smaller atomic radius than carbon. While moving down the periodic table, al
uminum comes before potassium even if they are not in the same period. So aluminum
's atomic radius will be smaller than that of potassium but bigger than that of carbon and oxygen.

The answer should be ....
A) Greece
Deductive reasoning is the step in biological methods,in which already well known scholars and scientists check the validity of proposed theory,they ensure that 100% accuracy is taken into account,for better result of new discoveries.
<span>L-amino acids and D-sugars are part of every protein.
All proteins are made up of them.
The fact that all biological systems use L-amino acids and D-sugars is linked with the idea that certain groups of organisms come from a common ancestor because. The reason is that if the common ancestors used L-amino acids and D-sugars, than its offsprings use them as well.

According to modern classification I will say that Jake is correct. With the use of tracing back and DNA technology then we can say that this is the digital way which is used nowadays to classify animals.
Sophie says through her observation that the characteristics of the animal classification used.
