Why are the noble gases (group 18) inert?

Chemistry
1 answer:
dalvyx [7]2 years ago
8 0

The noble gases are relatively unreactive because they have a stable octet of valence electrons.

Thus, they do not tend to undergo reactions in which they will gain or lose valence electrons,

However, <em>only He, Ne, and Ar are inert</em>. Kr and Xe combine with other highly reactive elements to form stable compounds.

Lakesha gave three tenths of her cookies to Bailey and five tenths of her cookies to Helen. What fraction of her cookies did Lak
Mashutka [201]

Answer:

a . eight tenths of her cookies

Explanation:

Let the total number of Lakesha's cookies be represented by x.

So that;

She gave three tenths to Bailey = \frac{3}{10} of x

                                                     = \frac{3x}{10}

She gave five tenths to Helen = \frac{5}{10} of x

                                                  = \frac{5x}{10}

Fraction of Lakesha's cookies given away = \frac{3x}{10} + \frac{5x}{10}

                                                      = \frac{3x+ 5x}{10}

                                                      = \frac{8x}{10}

Thus, the fraction of cookies given away by Lakesha is \frac{8}{10}.
