Li2 has a bond order of 1, calculated as (2 bonding electrons - 0 antibonding electrons)/2 = 1.

N2 has a bond order of 2, calculated as (number of bonding electrons - number of antibonding electrons)/2 = (10-6)/2 = 2.

O2 has a bond order of 2, while N2 has a bond order of 3, so none have a higher bond order than N2.

N2 has a bond order of 3, while O2 has a bond order of 2, so N2 has a higher bond order.

CO2 has a linear shape due to the arrangement of its double bonds.

PCl5 has five bonding pairs and no lone pairs, leading to a trigonal bipyramidal geometry.

N2 has a triple bond, consisting of one sigma bond and two pi bonds.

N2 has the highest bond order of 3, calculated as (10 bonding electrons - 2 antibonding electrons)/2 = 3.

F2 is diamagnetic as it has all electrons paired in its molecular orbitals.

C2 is isoelectronic with N2, both having 10 electrons.

N2 is isoelectronic with Ne, both having 10 electrons.

Ammonia (NH3) is polar due to its trigonal pyramidal shape and the presence of a lone pair on nitrogen.

Li2 is stable with a bond order of 1, while He2 and Be2 are not stable.

25.00 has 4 significant figures due to the trailing zeros after the decimal.

The number 100 has only 1 significant figure unless specified otherwise.

0.00560 has 3 significant figures, 0.0560 has 3 significant figures, 0.560 has 3 significant figures, and 5.60 has 3 significant figures. However, 0.00560 is the smallest number, but all have the same count of significant figures.

7.890 x 10^3 has 4 significant figures, while the others have 3, 3, and 4 respectively, but the leading zeros in the first and last options do not count.

0.0300 has three significant figures (the zeros after the 3 are significant because they come after a decimal point).

In the operation 3.00 x 4.0, 3.00 has three significant figures and 4.0 has two. The result will have two significant figures, which is the least among the options.

The 3s orbital has the highest energy among the given options due to its higher principal quantum number.

The 3d orbital is higher in energy than the 4s orbital due to its shape and electron repulsion.

A polar orbit allows a satellite to pass over the entire surface of the Earth as the Earth rotates beneath it.

Weather satellites typically use polar orbits to cover the entire surface of the Earth as the planet rotates beneath them.

Fluorine has the highest electronegativity among all elements.

Boron is a metalloid among the p-block elements.

Phosphorus is essential for life, particularly in DNA and ATP.

Boron is an essential micronutrient for plant growth.

Tin (Sn) is known for forming a stable +4 oxidation state.

Thallium is known for forming a stable +3 oxidation state.

Aluminum commonly forms stable +3 oxidation state compounds.
