Mardelev was the scientist who was the first person to discorver or invent the peridoic table!
Chemical reactivity first decreases.then it increases as we move across a period.
Decrease reactivity
Reactivity is not a change; it is a chemical property.
It's a table listing the elements, organized in columns of similar types of elements with respect to their chemical bonding characteristics, based on their atomic numbers and electron configurations.
