A Diatom is under the phylum of Chrysophyta with the following characteristics:
1) Unicellular but often colonial
2) manufactures the carbohydrate chrysolaminarin
3) has unique double -shells of opaline silica
4) contains chlorophylls a and c
They are abundant in sea and fresh water where they serve as producers.
Diatoms are protists that have glass walls. Just like plants, they carry out cytokinesis. They are photosynthesizers with hard shells of silica. An example of a Diatom is Diatoma.
Diatoms are divided into two major groups, one with radial symmetry and the other with bilateral symmetry.

In a double covalent bonds there are 4 valence electrons that are shared.
Basically all of the elements found in Group I of the periodic table also have this property. The ability to easily give up a single valence electron.
<u>Answer</u>:
By tracking oxidation numbers we can identify the number electron in the atom
<u>Explanation</u>:
Tracking of electrons helps us to know when and how many electrons get transferred from one atom to other atom . Oxidation referred as the “loss of one or more electrons” by an atom. When the oxidation number of an element increases, there is a loss of electrons and that element is being oxidized. Oxidation numbers are usually written with the sign (+plus or −minus) followed by the magnitude, which is the opposite of charges on ions. In their elemental stage oxidation number of an atom is zero.
