Brainlies ! 1. boron is to the immediate left of carbon in the same row in the periodic table. which of the following statements compares the radius and pull exerted by the protons of boron and carbon atoms? boron has a smaller radius and the protons in carbon exert a greater pull. boron has a larger radius and the protons in carbon exert a greater pull. boron has a smaller radius and the protons in carbon exert less pull. boron has a larger radius and the protons in carbon exert less pull. 2. which of the following is a compound? cl2 h2o he h2

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.
