No. Atoms differ in number of protons, neutrons and electrons.
They are the same
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
An atom's "group" is its column position in the Periodic Table of the Elements. Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level.
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
Isotopes are the same atoms with different masses. Example is carbon-12 and carbon-14
Elements in the periodic table have a unique number of protons in their nucleus, which determines their atomic number and identity. They also have characteristic properties based on their electron configuration, which influences their chemical behavior. Additionally, elements in the periodic table are organized based on their atomic structure and properties.
Such atoms belong to a group in the periodic table of elements.
Atoms whose symbols appear on a single row of a periodic table have the same number of electron shells. (Atoms with different numbers of protons represent different elements.)
Every element is composed of atoms, all with the same number of protons. The elements are distinguished by the unique number of protons in each of the nuclei of its atoms.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
In the Periodic Table Of Elements, elements are not necessarily similar under the same period. But, they are similar under the same group. they only have one thing in particular they have the same amounts of shells for the atoms
Elements in the same group on the periodic table have similar chemical properties because they have the same number of valence electrons. These valence electrons determine how atoms interact with other atoms, so elements in the same group typically exhibit similar reactivity and behavior in biological systems.
