<h3>Answer:</h3>
Potassium has the largest atomic radius.
<h3>Explanation:</h3>
Using periodic table trends one can easily compare the atomic radii of elements. The trends in atomic radii are as follow,
Trends in Groups:
Moving from top to bottom along the groups the atomic radii increases because as you move from top to bottom the number of shells increases hence, the distance of valence electrons from nucleus also increases and therefore, atomic radius increases.
Trends is Periods:
Moving from left to right along the periods the atomic radii decreases. This is because the number of protons and electrons increases but the the valence shell remain the same hence, causing more nuclear charge and more attraction between the valence electrons and nucleus.
<h3>Result:</h3>
Potassium, Calcium, Cobalt and Nickle all are present in same period. Potassium present at the extreme left will have greater atomic radii of 0.227 nm while Co and Ni at the middle of period will have atomic radii of 0.125 nm each. While, the atomic radius of Calcium next to K is 0.197 nm.
Answer:
By producing identical cells.
Explanation:
Mitosis:
It is a cell division in which DNA of original cell duplicate and produce identical copies The two new cells are called daughter cells having same genetic code to parent nuclei.
Importance of mitosis:
Mitosis play very important role in both unicellular and multicellular organisms.
In unicellular organisms it help in asexual reproduction. It produces identical copies of parent cell. For example in amoeba mitosis help to produce its new individual through cell division.
In case of multicelluar organisms mitosis also play an important role.
Regeneration of injured tissues:
It helps to regenerate and repair the injured cells by producing identical cells.
Growth:
It helps in the growth by producing new cells.
Genetic stability:
In mitosis chromosomes splits and produce identical copies therefore daughter nuclei are identical to their parents. It helps to maintain the genetic stability.
