True or False?
An element's reactivity is determined by the number of protons found in an atom of the element.
Answer (3)
False, I think. I would say it is determined by the number of electrons. The number of protons determines what element it is. An element will try and fill it's outer shell, and so elements such as neon (a noble gas) is difficult to do anything with as it already has a full outer shell of 8 electrons. Something with 7 outer electrons, however, will be much more reactive as they will try to fill up that last space through a chemical bond. Not sure if I explained that very well haha, basically i would say false
The** number of electrons found in the valence shell** of the element is determined the reactivity of the element. Therefore, the given statement is false.
Why do the elements in the same group have similar chemical properties?
The chemical behavior of elements is determined by the number of valence electrons in their outermost shell. Elements present in the same group contain the same number of valence electrons . Therefore, elements of the same group of the** periodic table **have similar chemical behavior.
In the periodic table, the elements having a similar outer electronic configuration in their atoms are placed in the** same group**. These valence electrons are responsible for the reactivities of the elements.
Whenever the atoms of an element react there will be a loss or gain of electrons . If the valence shell of an atom is incomplete, the atom will react to complete its valence shell.

The statement is False; an element's reactivity is determined by its valence electrons, not the number of protons. Valence electrons influence how atoms interact to achieve full outer shells, which determines their chemical behavior. Elements in the same group share similar properties due to having the same number of valence electrons.
