Sodium, Na, is in group 1 on the Periodic Table. The elements in group1 are the elements in that vertical column, which are Li,Na,K,Rb,Cs,Fr.
Apart from metals and non-metals, metalloids are also present. Transition elements are also present in periodic table.
The elements are classified as metals and non metals. Apart from this, there are elements that are metalloids, transition elements, inert in nature.
Uranium is a member of the actinides family of elements.
Apart from hydrogen, they are very reactive metallic (alkali) elements.
All the elements of the periodic table apart from hydrogen and helium are synthesised in the explosion of a supernova.
You think prpbable to ionic bonds.
Apart from Hydrogen, Helium and Beryllium; non metals are located in the p-block. Starting from the third period with addition of Li, all of s-block elements are metals. The d-block elements are a compete set of metals.
The Lanthanides consist of the elements in the f-block of period six in the periodic table. While these metals can be considered transition metals, they have properties that set them apart from the rest of the elements.
The Periodic Table of Earth is a visual representation of the chemical elements found on Earth. It is similar to the Periodic Table of Elements but includes only the elements that are naturally occurring on our planet. It provides a comprehensive overview of the elements and their properties, helping scientists understand the composition and behavior of Earth's materials.
Physical and chemical properties change somewhat regularly across a period. Elements that are close to each other in the same period tend to be more similar than elements that are father apart.
In the original periodic table by Dmitri Mendeleev, there were 62 known elements listed. What set Mendeleev's table apart from others around the same time is that he allowed gaps for elements that completed trends, and also included some elements that had not been completely confirmed at the time. At current, there are 118 elements in the periodic table, 6 of which have not yet been given an IUPAC name. All of the elements from Americium onwards are artificial, and not found anywhere in nature. Some other radioactive elements are present in nature, usually as decay products from higher radioactive elements.
