Since protons are postive and neutrons are neutral. Then it is postive.
The products for the complete combustion of a hydrocarbon in excess air is carbon dioxide and water. Any hydrocarbon when reacted with oxygen will always yield the said products. Incomplete combustion, on the other hand, yields carbon monoxide and water.
Answer:
A stir bar consists of a magnetic bar used to agitate a liquid mixture or solution
Explanation:
This is not the best way to organize a periodic table because two elements might have similar atomic mass.
<h3>What is periodic table?</h3>
Periodic table is a chart in which arrangement of chemical elements are done.
In the early periodic table elements are arranged on the basis of their atomic masses, while after sometime Moseley arranged the periodic table on the basis of atomic number as he proposed that properties of an element is justified on the basis of number if electrons.
And mass of two substances may be same so it is difficult to differentiate between them.
Hence, two elements might have similar atomic mass.

An element has no charge so its protons must be balanced with its electrons
so if X has 82 protons then it must have 82 electrons so that the atoms sum of charges adds up to 0
hope that helps
