A carbon-12 atom has 6 protons, 6 neutrons, and 6 electrons. how many protons does a carbon-14 atom have?
2 answers:
Answer: Option (a) is the correct answer.
Explanation:
As the given atom is so, it means that it contains 6 protons. Also, when an atom is neutral then its number of protons equal to the number of electrons.
Atomic mass means the sum of total number of protons and neutrons present in an atom. As is an isotope of
. And, all the isotopes of carbon or any other element contains the same number of protons but different number of neutrons.
Therefore, there will be 6 protons present in .
Thus, we can conclude that carbon-14 atom have 6 protons.

Answer:
Option "B" is correct.
Explanation:
According to VSEPR theory, There are repulsion forces exists among the bond pair - bond pair or bond pair - lone pair of electrons. In and
, the number of electron pairs are same but methane has all the four bond pairs where in ammonia, three bond pairs and one lone pair exists. And thus there are repulsion forces possible in between the lone pair and bond pair of electrons thus the arrangement of electron pairs around both the molecules is same or different depending up on the conditions leading to maximum repulsion.
