an atom has 8 electrons and a mass of 17. what would the correct symbol be?

a
178o
b
179f
c
98o
d
2517cl

O₈¹⁷

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.

In given statement there are 8 electrons it means the atomic number of given atom is 8 so it would oxygen. The atomic mass of oxygen is 16 while in given statement mass is 17 it means it is the isotope of oxygen that have one more neutron than oxygen 16.

Isotope of an element have same atomic number but different atomic mass due to different number of neutrons.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
