Explanation:
The electronic configuration of a lithium atom is 2.1 and that of a fluorine atom is 2.7
an atom of lithium donates an electron to an atom of fluorine to form an ionic compound. The transfer of the electron gives the lithium ion a net charge of +1, and the fluorine ion a net charge of -1.
Evidence for evolution reveals that closely related organisms have many similar physical and genetic characteristics.
Explanation:
Closely related organisms have similar physical features and genetic sequences.
When both the physical and genetic features are similar, these organisms are referred to as homologous structure.They are similar, as their evolutionary path is the same.
Example: bones from the birds and arms of the humans, have evolved more or less similarly so they are homologous structure.
In other cases, the organisms might be closely related, but their genetic structure might have a slight change. Due to this change there might be difference in the physical structure.
Example: the chimpanzee and human have different physical structure even though their evolution have taken the same path and they are closely related.
