Answer:
Ne with eight dots
Explanation:
On the periodic table, Neon is in group 8A. The group can be used to determine the number of valence electrons.
The dots in the Lewis structure diagram represent the number of valence electrons.
It showed that atoms can be divided into smaller parts.
It showed that all atoms contain electrons.
Explanation:
The experiment carried out by J.J Thomson on the gas discharge tube by passing electric current through a tube filled with many different gases provided a good insight into the structure of an atom.
This experiment led to the development of the plum pudding model of the atom.
- Cathode rays and it properties were discovered in this set up.
- It furnished the scientific community with evidences that atoms can be divided into smaller parts.
- Since atoms now contain some subatomic particles, they can be broken down in like manner into further bits.
- The cathode rays which were later termed electrons became a fundamental particles known for every atom.

Chemical Reaction
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. Substances are either chemical elements or compounds.
In a chemical change, new substances are formed. In order for this to occur, the chemical bonds of the substances break, and the atoms that compose them separate and rearrange themselves into new substances with new chemical bonds. When this process occurs, we call it a chemical reaction. A chemical reaction is the process in which one or more substances are changed into one or more new substances.In chemical reactions, atoms are never created or destroyed.

Paper made from linen is "less" acidic while wood paper is more acidic which also explains which lasts longer. In general, papers that are less acidic don't last as long as papers that aren't as acidic such as linen. Therefore, linen paper lasts longer than wood paper.
