As a metal, lithium will lose electrons to have a ful valence shell. How manyvalence electrons will it lose to have full valence
Free_Kalibri [48]

Answer:

It will lose 1 electron

Its charge will be 1+, or simply (+)

Explanation:

Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.

The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+

For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+

Why are plants important to the carbon water and nitrogen cycles?
dezoksy [38]

Answer:

The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.

Explanation:

Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.

Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.

Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!
