Why does group 18 in the periodic table not form ions?

Chemistry

Lets take a moment to list all the characteristics of the group 18 (also known as noble gases and/or group 8) elements: 
- They have 8 valence electrons. 
- Don't need ANY more electrons because their octet is full (stable). 
- Are stable 
- Not reactive
- Known as the noble gases

Now.. lets take some time to think about why elements want to form ions: 

Elements form ions to either gain or lose valence electrons to the element they bond with. This helps them GAIN a full octet. What is a full octet, you may ask? An octet is when an element has all 8 valence electrons and is stable, making it nonreactive. 

Why would an element with a full octet want to bond? It already has a full octet, it does not need to bond. 

That, my fellow Brainly user, is why the noble gases do not need to bond. 

I really do hope this helps! Enjoy, and good luck on the studies.

Convert 35kg to its equivalent in g using dimensional analysis
Masteriza [31]
(35 kg)*(1000 g / 1 kg)

(35 kg / 1 kg)*(1000 g)

kg units cancel, you're left with units of g

35/1*1000 = 35,000

ANSWER:

35,000 g

Why is zinc not extracted from ZnO through reduction using CO?​
Jet001 [13]
The standard Gibbs free energy of formation of ZnO from Zn is lower than that of CO2 from CO. Therefore, CO cannot reduce ZnO to Zn. Hence, Zn is not extracted from ZnO through reduction using CO

What is the best example of an experimental scientific investigation?
ivolga24 [154]

Scientific investigation: The process in which scientist solve the question by using different systematic approach. It can be initiated in different ways.

Experimental Scientific investigation: The investigation in which scientist answer the question on the basis of experimental results. Experimental investigation includes both dependent and independent variables, and only one variable is tested at a time is possible.

The best example of an experimental scientific investigation is: when we placed a whole apple and apple slice under sun, and noted down how many days it will take to  rot in order to compare the break down of apple slice and whole apple.

Thus, option (B) is the correct answer.
