How to find the valence electrons on a periodic table + energy levels?

Chemistry
1 answer:
Zigmanuir [339]3 years ago
3 0
The answer is elements in the first row (hydrogen and helium) will have outer electrons in the first energy level. Their principal quantum number is 1. Elements in the second row (lithium through neon) will have valence electrons in the second energy level with a principal quantum number of 2. I hope that helps.

Jarvis checked his odometer reading when filling his tank, and then checked it several days later when he filled his tank again.
8_murik_8 [283]

Answer: 26.25 miles per gallon

Explanation: first odometer reading = 65290

Second odometer reading = 65500

Difference in odometer reading = second reading - first reading

= 65500 - 65290 = 210 miles.

If it took 8 gallons to fill his tank, it means

8 gallons will get him 210 miles, therefore 1 gallon will get 210 miles/8gallons = 26.25miles/gallon. Hence he is getting 26.25miles/gallon.

The reaction is a synthesis reaction.

<h3>What are synthesis reactions?</h3>

Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.

Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.

The different elements that combine are referred to as the reactants while the result of the combination is known as the product.

For example: A + B --> AB

In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.

This is a good example of a synthesis/combination reaction.
