3. Riya observes some cattle grazing in the field near her house every day. But one thing that fascinates her is that these animals are always chewing even when they
are not eating grass.
a) Why do these animals chew even when not engulfing/eating?
b) What is this process known as and state the biological reason behind it?
c) Can we also perform this? Give reason for your answer.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
