Question

2. How many protons, electrons and
neutrons are present in the following
atoms ? Also indicate the atomic number
and mass number



Don't send wrong answers u don't know means leave others will try ​

Answer 1

1. Oxygen

No of protons = 8.

No of electrons = 8

Number of neutrons = 16-8 = 8

Atomic Number = 8

Mass Number = 16

2. Copper

No of protons = 29

No of electrons = 29

No of neutrons = 64 - 29 = 35

Atomic number = 29

Mass number = 64

3. Phosphorus

No of protons = 15

No of electrons = 15

No of neutrons = 31 - 15 = 16

Atomic number = 15

Mass number = 31

4. Potassium

No of protons = 19

No of electrons = 19

No of neutrons = 38 - 19 = 19

Atomic number = 19

Mass number = 38.

5. Tellurium

No of protons = 22

No of electrons = 22

No of neutrons = 47 - 22 = 25

Atomic number = 22

Mass number = 47

Hope this helps. Please mark as brainliest

Answer 2

1)E=8,p=8,n=8

2)E=29,p=29,n=35

3)E=15,p=15 ,n=16

4)E=19 ,p=19 ,n=20

5)E=52 ,p=52,n=76
