Sorting the chemical elements in order from least reactive to most reactive, we have:
1. Fluorine (F).
2. Arsenic (As).
3. Antimony (Sb).
4. Silicon (S).
<u>Given the following chemical elements:</u>
Reactivity can be defined as a chemical property which determines how readily a chemical element <u>bonds</u> with other chemical elements, in order to form a new chemical compound.
Generally, the ability of a chemical element to bond with other chemical elements is largely (highly) dependent on the number of valence electrons it has in the outermost shell of its atomic nucleus.
As a general rule, chemical elements that are having <u>fewer</u> number of valence electrons are the most reactive while those having <u>higher</u> valence electrons are least reactive.
Also, chemical reactivity <u>decreases</u> down a group on the periodic table.
Based on the periodic table, the valency for the given chemical elements are:
- <u>Antimony (Sb):</u> 5 valence electrons.
- <u>Silicon (S):</u> 4 valence electrons.
- <u>Fluorine (F):</u> 7 valence electrons.
- <u>Arsenic (As):</u> 5 valence electrons.
In conclusion, sorting the chemical elements in order from least reactive to most reactive, we have:
1. Fluorine (F).
2. Arsenic (As).
3. Antimony (Sb).
4. Silicon (S).

Answer:
128.4 m
Explanation:
3.604m + 104.29m + 3.1m + 17.41m
Add all the values
= 128.404 m
The significant figure rule for addition is for the sum to have the same number of decimal places as the value with the least number of decimal places. In the addition sentence 3.604m + 104.29m + 3.1m + 17.41m, the value with the least number of decimal places is 3.1, which has 1 decimal place. Therefore, we round our sum so that it also has 1 decimal place.
128.404 m
= 128.4 m
