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.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

The answer is option a
