False. An element's reactivity is determined by the number of electrons in its outermost energy level, rather than the number of protons in its nucleus. Elements with fewer electrons in their outer shell are more likely to react with other elements in an effort to achieve a stable electron configuration.
This element is chlorine and is very reactive.
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
The number of protons in each element is determined by the atomic number of the element. The atomic number corresponds to the number of protons in the nucleus of an atom. This number is unique to each element and is determined by the arrangement of electrons and protons in the atom.

No, an element's reactivity is mainly determined by the number of electrons in its outer shell, known as valence electrons. Elements with fewer valence electrons tend to be more reactive as they seek to either lose, gain, or share electrons to achieve a stable electron configuration. The number of protons in an atom, which determines the element's identity, does not directly influence its reactivity.
False. An element's reactivity is determined by the number of electrons in its outermost energy level, rather than the number of protons in its nucleus.

An element can be identified by the number of protons in the nucleus of its atoms.
Yes, it is the atomic number i.e. number of protons that determines an element's identity.
The properties of elements are determined by their atomic structure, including the number of protons, neutrons, and electrons. The arrangement of these particles within an atom influences an element's chemical and physical properties. Characteristics like reactivity, melting point, and conductivity are all tied to an element's atomic structure.
This element is chlorine and is very reactive.
Moseley determined that the number of protons in the nucleus of an atom corresponds to the element's atomic number. This discovery led to the modern periodic table where elements are arranged in increasing atomic number.
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
The element won't stay the same because the element is determined by its number of protons. The number of protons is also the atomic number.
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
