Hint :The periodic table was created when the periodic recurrence of comparable features among the elements was discovered. The elements are organised in rows called periods and columns called groups in order of increasing atomic number. Chemical characteristics are comparable among elements in the same periodic table group.
Complete Step By Step Answer:
Elements are the simplest chemical substances in which all of the atoms are identical. We may characterise elements as a group of atoms with the same number of protons in their atomic nuclei. While an element's atoms all have the same amount of protons, they may have different neutron counts and hence different masses. Metals, metalloids, and nonmetals are the three types of elements, whereas main-group elements, transition metals, and inner transition metals are the three types of transition metals. From left to right, the groups are numbered 1–18.
Elements made of metal.
Metals make up the majority of the elements in the periodic table. Alkali metals, transition metals, lanthanides, actinides, and alkaline earth metals are all metals. On a periodic table, metals are separated from nonmetals by a zigzag line that runs from carbon to radon. Phosphorus, selenium, and iodine are the elements that separate the two. Nonmetals are these and the elements next to them in the periodic table. Semimetals or metalloids are elements that exist just to the left of the line. These will have qualities that are a mix of metals and nonmetals.
Non-metals make up a small percentage of the periodic table. These may be found on the periodic table's right-hand side. Sulphur, carbon, all halogens, phosphorus, hydrogen, oxygen, selenium, nitrogen, and noble gases are all non-metals. Non-metals are found to the left of halogens and to the right of metalloids in the periodic table. Noble gases and halogens are commonly referred to as non-metals since they are non-metals as well.
Metalloids are a tiny group of elements found in the periodic table of elements between boron and aluminium and between polonium and astatine, along the zig-zag line that separates metals from nonmetals.
Many elements have vastly different chemical and physical characteristics, yet some have behaviours that are quite similar. Many elements, for example, are lustrous, malleable (able to be bent without breaking), ductile (able to be made into wires), and transfer heat and electricity well. Other elements are not lustrous, malleable, or ductile, and are poor heat and electrical conductors.
