The reactivity of an element is influenced by several factors, including the number of electrons in its valence shell, the number of protons in its nucleus, its atomic radius, and the number of neutrons in its nucleus. The number of electrons in the valence shell determines how easily an atom can gain or lose electrons, which affects its reactivity. The number of protons in the nucleus determines an atom’s atomic number and its position on the periodic table, which can influence its reactivity. The atomic radius, or the distance from the nucleus to the outermost electron shell, can affect the reactivity of an atom by determining how easily it can interact with other atoms. The number of neutrons in an atom’s nucleus does not directly affect its reactivity but can influence its stability and, indirectly, its reactivity.
Define atomic properties as characteristics that describe the behavior and structure of individual atoms.

Now, what makes an element metallic? It’s all about electrons, the tiny particles that whizz around the atom’s nucleus. Metallic elements have valence electrons, the ones on the outermost shell, that are like party animals who love to roam freely. These electrons can easily jump around and mingle, allowing metals to conduct electricity like a rockstar.
The more valence electrons an element has, the more metallic it is. So, elements in the far left of the periodic table, like alkali metals (Group 1), have a party of valence electrons and are the ultimate metalheads.
On the flip side, elements on the far right of the table, known as halogens (Group 17), are anti-metal party poopers. They only have one or two valence electrons, so they’re not into the whole electron-sharing scene.
Now you know why metals are the shining stars of conductivity and why halogens are the lone wolf electrons of the periodic table. Understanding atomic properties is like having a cheat sheet to the universe, allowing you to predict an element’s behavior based on its atomic characteristics.
