Brief note on Blastula ion in Amphioxus

The rhird cleavage planes involve four blastomeres and are transverse dividing each blastomere into upper four smaller micromeres and lower megameres to the vegetable.

How does an ion differ from an atom ?

When an atom gains one or more electrons, a negatively charged ion is formed. Positively charged ion is called cation, and the negatively charged ion is called anion. Thus, A cation (positively charged ion) is formed when an atom loses one or more electrons.

Are the properties of an atom and an ion similar ?

No. the properties of an atom of any element are quite different from those of its ion. Ion is formed due to loss or gain of electron from an atom. In doing so, each atom acquires an electronic configuration of the nearest noble gas.

How is the charge on an ion calculated ?

Atoms are electrically neutral. A positive ion (or cation) is formed when an atom loses one or more electrons. An electron carries one unit of negative charge. So, the number of units of positive charge only a cation is equal to the number of electrons lost by the concerned atom.
