The first twenty elements are made up f different things
In the Periodic Table of Elements there are: 118 Observed Elements 114 Officially Discovered Elements 112 Officially named Elements 92 Naturally Occuring Elements 83 Non-radioactive elements
Group 1 elements are called alkali metals and all have a single electron in their outer shell/valence shell. These alkali metals are: Lithium (Li) Sodium (Na) Potassium (K) Rb (Rubidium) Caesium (Cs) Francium (Fr)
Lithium, sodium and potassium are all group I elements. They are also called alkali metals. They react violently with water to form strongly alkaline solutions. The elements, as we descend the group in the periodic table, become increasingly reactive.Li Na K are alkali metals. They are present in group-1. They have one valence electron.All of these elements are located in group 1 of the periodic table. Each of these elements are highly reactive metals. They react with acids to produce salts. All of these are good conductors of electricity and heat.Li,Na and K are in the 1st group of the periodic table. They are alkaline metals. They all have a valency of 1.
When looked at the periodic table its u will see that each column has a # on the top of the periodic table...group 1 is the 1st column to the left & are the alkaline metals...the last column all the way to the right of periodic table are nobel gases..for example. Transition metals are all the elements in groups # 3-12. (In between where the metals & the non metals locations on the P.T). Hope that helps!
Oh, dude, butane is not actually found on the periodic table because it's a compound, not an element. But if you break it down, it's made up of carbon and hydrogen atoms, which you can find on the periodic table. So, like, it's a team effort, you know? Carbon and hydrogen coming together to create butane, the unsung hero of lighters everywhere.

Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.
All except neon and helium
Nitrogen can be found in the 1st period of group 15 elements in the periodic table.
He created the first periodic table of elements, arranged by atomic mass. His greatest accomplishment, however, was his ability to predict missing elements using this periodic table, and that is why he is considered the Father of the Periodic Table of Elements.
hydrogen is an element of the periodic table and has the symbol H. hydrogen has 1 electron and is 1st on the periodic table.

The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.
Group 1 elements are called alkali metals and all have a single electron in their outer shell/valence shell. These alkali metals are: Lithium (Li) Sodium (Na) Potassium (K) Rb (Rubidium) Caesium (Cs) Francium (Fr)
The two rows of metals that appear at the bottom of the periodic table are the lanthanides and actinides. They are known as the inner transition metals and are placed below the main body of the periodic table to keep the table size manageable.
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
The periodic table orders elements by its number of protons. The 1st element has 1 proton, the 2nd has 2, and so on. Furthermore, elements with similar characteristics are grouped vertically. These elements(1A-8A) have the same number of electrons in their outer shell, so react similary. Elements organized horizontally have progressively more protons and electrons.
