What is the periodic table?
The periodic table of elements is basically a chart that shows you information of every known element. The periodic table is organized in a way that allows you to figure out things such as how many valance electrons each element has while still maintaining numerical order while simultaneously positioning each element to each group; such as noble gasses, transition metals, alkaline metals, and so on. In this article, I will be discussing as many elements as possible; starting with hydrogen.
What is hydrogen?
Hydrogen has 1 proton, making its atomic number 1, and it the first on the periodic table; numerically, not historically. Hydrogen is a gas at room temperature and has a lower density than the atmosphere here on Earth; making it viable substance to be put in balloons.
Although it can also be very dangerous. This is because hydrogen is flammable; if a balloon filled with hydrogen was exposed to a large amount of heat, the balloon would make a medium-small explosion.
What is helium?
Helium is the second element on the periodic table. In normal situations, it has 2 protons and 2 neutrons; if the nucleus of an atom had a different number of neutrons from its number of protons, it would be an isotope.
A neutron's purpose is to act like a barrier. Since protons have a positive charge, they would push each other away. A neutron weakens that push so atomic forces can push the protons together.
Helium's most common use is to fill balloons and other things to provide lift due to its density being lower than that of normal air; air is composed of 78% nitrogen and 21 percent oxygen. Although hydrogen is lighter and cheaper, it is also flammable; this makes hydrogen a dangerous gas to use in balloons.
To be continued...
