Concept introduction:

Mostly, the elements are found as single atom particles in the universe. For example, the element which exists in the gas phase as single atoms at temperatures is Helium and the element which found in the solid phase is Lithium. The elemental symbol is used to denote this one atom elements and further explain that these atoms are uncombined in nature. The elements which are in between metals and non-metals are denoted as metalloids or semi metals. When atom accepts or loses electrons it is termed as ion. If the ion loses an electron and accepts a positive charge it is called as cation. Similarly, if the ion gains an electron and accepts a negative charge it is called an anion. When the ion is formed from a single atom, it is referred as monatomic ion.
