3- If element Z has 15 protons & 17 neutrons. What are its number of electrons, atomic number & mass number? ____________

4- If element A has 7 electrons & 9 neutrons. How many protons does it have? And what is its atomic number? ____________



1- If the atomic number of an element is 15 & its mass number is 31? How many protons & neutrons does this element have? _______



2- If element B has 9 electrons. Find the number of protons & atomic number. ______________



3- If the mass number of element A is 60 & number of neutrons is 33. Find its number of protons & its atomic number. ______________

Answer 1

1. 6electrons because in an a neutral atom, the number of electrons and protons are equal

2. Atomic number is 10

3. 15electrons, Atomic number 15,Mass number 32

4. 7protons, Atomic number 7

1. 15protons,16neutrons

2.Number of protons is 9, atomic number is 9

3.Number of protons is 27, Atomic number is 27

Step-by-step explanation:

The mass number (A)=Atomic/proton number (Z)+Neutron number (N)
