The number of valence electrons and electronegativity of an element in the unknown element determines the other elements it reacts with.

<u>Explanation:</u>

The ability of an atom to attract the electrons for bonding is called electro negativity. When an atom has highjer electronegativity it can attract electrons stronger. When the atom's electronegativity is lower it can attract electrons weaker. This property is very important in the determination of how well an element can readily react with another element.  

The determination of an element's reactivity can also be done  by the number of valence electrons in the outermost shell. The elements that has valence electrons lesser than 4 will be giving its valence electron for getting 8 electrons in the next shell so that it can become an ion of stable nature. An element that has 4 electrons will form covelant bond. The elements that have greater than 4 electrons will be getting electrons from some other element.

What is true about protons within an atom?
Ira Lisetskai [31]
It defines the element. If you change the protons, you change the type of element. A proton is positively charged and is most of the mass of the atom, next to the neutron. Neutrons have a very very very slightly higher mass.

Which quantum number distinguishes the different shapes of the orbitals?
UkoKoshka [18]
The four quantum numbers are:
principle quantum number: this number describes the energy of orbitals. It describes the most probable distance between the electron and the nucleus.
angular quantum number: this number describes the shape of orbitals, and thus, describes the angular distribution.
magnetic quantum number: this number describes the number of orbitals and how they are oriented within the subshell
spin quantum number: this number determines the direction of the spin of the electron.

Based on the above, the quantum number that distinguishes the different shapes of the orbitals is the angular quantum number
