Question

Locate the element zinc (Zn) on the periodic table. How many protons does an atom of zinc contain? How many electrons does an atom of zinc contain? How many neutrons does an atom of zinc contain? Give your answer to the nearest whole number.

Answer 1

Answer: Number of protons and electrons in Zinc are 30 and number of neutrons in zinc are 35.

Step-by-step explanation:

Zinc is the 30th element of the periodic table having mass number of 65.

• Atomic number is defined as the number of protons or number of electrons present in an element. It is represented as Z.

Atomic number = Number of protons = Number of electrons

For Zinc:

Z = 30

So, Number of protons = Number of electrons = 30

• Mass number is defined as the sum of number of protons and number of neutrons. It is represented as A.

Mass number = Number of neutrons + Number of protons

A = 65

So, Number of neutrons = 65 - 30 = 35

Hence, number of protons and electrons in Zinc are 30 and number of neutrons in zinc are 35.

Answer 2

Part 1:

Location the element zinc (Zn) on the periodic table:

• Group number : 12
• Period number : 4
• Block : d block
• Element : Transition elements.

Part 2:

Protons in an atom of Zn: 30

Part 3:

Electrons in a Zn atom: 30

Part 4 :

Neutron in an atom of Zn: 35
