What does the atomic weight of an element represent
Marrrta [24]

The nuclei of atoms also contain neutrons, which help hold the nucleus together. ... The total weight of an atom is called the atomic weight. It is approximately equal to the number of protons and neutrons, with a little extra added by the electrons.


The mass of a given atom, measured on a scale in which the hydrogen atom has the weight of one. Because most of the mass in an atom is in the nucleus, and each proton and neutron has an atomic weight near one, the atomic weight is very nearly equal to the number of protons and neutrons in the nucleus.

How many hydrogen atoms are present in a hydrocarbon chain of 8 carbon atoms with 3 double bonds and the rest single bonds
romanna [79]

11 hydrogen atoms are present in the hydrocarbon chain having 8 carbon atoms with 3 double bonds.

<h2>Number of hydrogen atoms</h2>

There are 11 hydrogen atoms present in a hydrocarbon chain of 8 carbon atoms with 3 double bonds and the rest single bonds because 5 hydrogen atoms make a single covalent bond with carbon atom whereas the 6 hydrogen atoms make a double covalent bond with carbon atom.

<h3>Double bond</h3>

In double bond, one atom bonded with two atoms so we can conclude that 11 hydrogen atoms are present in the hydrocarbon chain having 8 carbon atoms with 3 double bonds and 5 single bond.
