If a chlorine atom were to attract an extra electron from lithium, the lithium atom would become charged.

If a chlorine atom were to attract an extra electron from lithium, the lithium atom would become positively charged.

A Lithium atom has two electrons orbiting in the inner shell and only one electron orbiting in its outermost shell. The outer shell is incomplete and therefore unstable.

Lithium atoms readily give up one electron to form a positively charged  Lithium ion. In so doing , it obtains the same stable configurations as the noble gas helium.

All group one atoms can lose one electron to form positively charged ions.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
