Question

Oxygen has three isotopes of atomic masses 16, 17 and 18 respectively. Explain the following:

(i) They have same chemical properties.

(ii) They are all electrically neutral.

​

Answer 1

Answer:

hiii

your answer is here !

Explanation:

(i) Mass numbersof isotopes of oxygen are different, i.e.,16, 17 and 18 but they have same atomic number 8.Thus, the number of electrons is same.Therefore, they have same the electronic configuration 2, 6 and same number of valence electrons.So,their chemical properties are same.

(ii) They are electrically neutral because number of negatively charged electrons is same to the number of positively charged protons.

follow me !

Answer 2

Answer:

hlo mate here is ur answer..

Explanation:

The three isotopes have same chemical properties but different physical properties as they are in different states

They are electrically neutral coz electric charge on the ion is determined by the number of electrons and protons in the orbital shell..

hope it helps u dear.. ❤
