Answer:
No.
Explanation:
According to the formula б/X=б/√n, as more measurements are made, the uncertainty gets smaller.
nitrogen (N), antimony (Sb), bismuth (BI)
Explanation:
Electrical conductance increases from Nitrogen to antimony and then Bismuth. Electrical conductance increases with available free electrons.
- The elements listed belongs to Group V on the periodic table.
- Group V elements are Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth.
- As we go down the group, electrical conductance increases.
- This is because the radius of the atom becomes larger and the pull on the outer electrons become very weak.
- Outer electrons becomes free to facilitate electrical conductance.
- We can also see that metallicity i.e electropositivity increases down the group.

The question is incomplete, the complete question is;
The Lewis representation above depicts a reaction between hydrogen (blue) and a main-group element from group______ (red).
In this representation, each Y atom needs ______ electron(s) to complete its octet, and gains these electrons by forming______ bond(s) with atoms of H .
There are ______ unshared electron pair(s) and _______bonding electron pair(s) in the product molecule.
The bonds in the product are _________ (Ionic or Covalent)
Answer:
1) 16
2) 2 electrons
3) 2 bonds
4) 2 unshared pairs of electrons
5) 2 bonding pairs of electrons
6) The bonds in the product are covalent
Explanation:
Group sixteen elements have six electrons on their outermost shell. These include two unshared pairs of electrons and two unpaired electrons. These two unpaired electrons can now be covalently bonded to two hydrogen atoms to give H2Y. The compound H2Y has two lone pairs and two bond pairs of electrons.
H2Y can be a general formula for all hydrides of group 16. They are all very similar in structure but gradually differ in physical and chemical properties according to the graduated variation observed down the group.
Rounded to 1 significant figure, 25 m would go to 30. This is because 0 isn't significant, so the 3 is the only significant figure.
