Why does the lithium atom develop a positive charge?​

Chemistry
1 answer:
nikitadnepr [17]2 years ago
6 0

Answer:

Lithium develops a positive charge because it has one valence electron. Instead of lithium trying to steal 7 electrons from other elements to obtain an octet, it is easier to lose its one electron to become stable. Because neutral atoms contain the same amount of protons and electrons, when lithium loses one electron, there is one more proton than electrons.

In other words

Lithium has 3 protons and 3 electrons in its neutral state, but it loses one electron to become stable so it now has 3 protons and 2 electrons, and there is one more proton than electrons: +3 -2 = +1 charge

What is the primary reason why elements form compounds?​
zheka24 [161]

Answer:

To gain stability

Explanation:

If the outermost shell is not completely filled with electrons, the element has one of the three options: gaining electrons, losing electrons or sharing electrons. By gaining or losing electrons, ionic compounds are produced. Sharing of electrons results in the formation of covalent compounds.

If 25.0 g NO are produced, how many grams of nitrogen gas are used?
mr Goodwill [35]

Using the stoichiometry of the reaction and the information provided in the question, the mass of N2 used is 11.62 g.

<h3>Chemical reaction</h3>

The term chemical reaction refers to the combiantion of two or substances to yiled one or more products. The reaction equation in this case is N2 + O2 --->2NO.

Now;

Number of moles of NO = 25g/30 g/mol = 0.83 moles

1 mole of N2 yields 2 moles of NO

x moles of N2 yileds 0.83 moles of NO

x = 0.415 moles

Mass of N2 = 0.415 moles * 28 g/mol = 11.62 g
