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.

Explanation:
They put five crickets in each of three identical containers. They s ... to 15°C, one to 20°C, and one to 25°C. Then they count the number of cricket chirps in each container
The answer is C but i might be wrong
Sp2 hybridization forms 1 sigma bond and 1 pi bond.
Blank 1: polar
The difference in electronegativity between N and H causes electrons to preferentially orbit N, making the bond polar.
Blank 2: trigonal pyramidal
There are four “things” attached to N - 3 H’s and 1 lone pair of electrons. The four things together are arranged into a tetrahedral formation. However, the lone pairs don’t actually contribute to the shape of the molecule per se; it’s only the actual atoms that do. The lone pair creates a bit of repulsion that pushes the 3 H’s down, creating a trigonal pyramidal shape (as opposed to a trigonal planar one).
Blank 3: polar
The molecule as a whole is also polar because the “things” around it, though arranged in a tetrahedral pattern, are not all the same. The side of the molecule with the lone pair is slightly negative, while the side with the 3 H’s is slightly positive due to the differences in electronegativity described above.
