2.An atom with 35 mass number has 17 proton in its nucleus. Find the number of
neutron. What is its atomic number?​

mass no = A

Atomic number = Z= no of protons

Neutron = n

n = A-Z

n= 35- 17

   = 18

Explanation:

ill try to . no promises tho.

explanation:

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
