The periodic table was formed in the 19th century by Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights, creating the foundation for the modern periodic table we use today.
If you randomly select an element from the periodic table, it is more likely to be a metal. Metals make up the majority of elements on the periodic table, followed by nonmetals, and then metalloids, which are less common.
Horizontal rows are called groups. Groups are formed according to the atomic number.
The elements in Group 17 of the periodic table, also known as the halogens, contain elements that behave as strong oxidizing agents.
Element X would most likely be found in the alkali metal group on the far left of the periodic table.
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
Be stands for Beryllium in the periodic table of elements. It is a light and strong metal that is commonly used in aerospace and defense industries due to its high stiffness-to-weight ratio.
If the xkcd periodic table was used to create a new element, it would likely be a fictional or humorous element, as the xkcd periodic table is not based on scientific accuracy.
