dropping by 20-25˚ F and barometric pressure dropping by 15-20 mb. Snow beginning 30-36 hours from now, accumulation of 10-13 inches possible. Cooler temperatures and clear skies in 2 days.”
In the periodic table, the atomic radius of the atoms decrease from left to right. This means that Carbon is smaller than Boron. So from the choices you can rule out the first and third choice.
Now, the reason why Carbon is smaller than Boron is because Boron has more protons and as the protons increase it attracts the electrons closer, which makes the atom smaller.
Carbon has more protons, so it exerts a greater pull. The answer is then Option 2: Boron has a larger radius and the protons in carbon exert a greater pull.
As for the second question, a compound is defined as a substance that is made up of two DIFFERENT elements that are chemically bonded. If you look at the second option, it is a compound. It is made up of hydrogen and oxygen atoms.
The answer is then option 2.
