Question
Bohr 's shell model also explained why some of the elements in the periodic table are chemically inert. This is because the outermost shell of the atom is full. These elements are called ______.
Open in App
Solution
The correct option is D noble gases
Bohr was first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element. The elements in table 1 of the periodic table are known as the alkali metals. They are highly reactive in air and water, as they have only one electron in their outermost shell. They easily donate this electron. The halogens are ones that easily accepts electrons and are also very reactive. The metals present in the middle of the periodic table can donate electrons to attain stability. Nobel gases are the elements present in the last row of the periodic table, they are inert in nature because their outermost shell is completely filled and there is no vacant orbit for other electrons to accommodate.
