The numbers of protons and neutrons in its nucleus, and the number of electrons in its valence shell. The number of protons and neutrons will affect the element and the isotope number, some isotopes are stable, some are not. Atoms are also more stable with a full outer energy level (octet rule - 8 electrons in the outermost shell).

∙ 9y agoWhen an atom loses or gains electrons to have a filled valence level, the atom is called ion and said to be stable. When the number of protons equal the number of electrons the atom is said to be neutral, which has no charge.

∙ 12y agoThe number of electrons in the orbits determines the stability of atoms.An orbit can accomodate a maximum of 2n^2 electrons(where n is the order of the orbit from nucleus 1,2,3,....)however an atom need 8 electrons in its valence shell(outer most shell) to attain a maximum stability.

Where is the special feature that determines the family name and chemical reactivity of the organic compound it is found?
Functional Group
The reactivity of an atom arises from what?
the existence of unpaired electrons in the valence shell. :)
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
What determines an element's reactivity?
The electrons determine the reactivity. How many valence electrons there are. It is easier to lose one electron rather than three, so an element with one valence electron will be more reactive than one with three.
What determines the chemical activity of an atom?
The nucleus of an atom (protons and neutrons) determines if an atom is radioactive. The tendency is, the larger the nucleus, the more unstable it is and the more likely it is to be radioactive. As for the chemical bonding properties of the atom, the electron configuration determines how it will bond, with what it will bond, and in what ratio atoms will bond to form the 20,000,000 different substances on Earth.
What determines a compounds reactivity in an SN2 reaction?
Stearic hindrance and stability of carbonium ion, less stearic hindrance and less stability of carbonium ion favors the SN2 reaction.
How is the chemical stability of a mineral is related to the temperature at which the mineral forms?
The strength of the minerals chemical bond between its atom determines its chemical stability .
What determines an atom behavior?
The largest determinant to an atom's behavior is its electron configuration. An atom's electron configuration determines its interactions with other atoms, such as which atoms it can form bonds with and whether that bond is covalent or ionic. Additionally, the number of neutrons and protons influence the stability of the atom's nucleus.
What is the reactivity of an atom determined by?
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
The stability of an atom is determined by the what?
The stability of an atom is determined by the:
How the chemical stability of a mineral is affected by the bonding of the atoms in a mineral?
the chemical stability of minerals is depedent on the strength of the chemical bonds between atoms in the mineral.
What is the chemical behavior of an atom is determined by?
By using the activity series (sometimes called reactivity series) which orders metals by their reactivity with other metals, one can determine the reactivity of a metal
What are the properties of reactivity?
Reactivity refers to how vigorously an atom is to react with other substances.
What is the definition of a ligand as used in chemistry?
Ligand is an atom, ion, or molecule that donates or shares one or more of it's electrons through a covalent bond with a central atom or ion. It is a complexing group in coordination chemistry that stabilizes the central atom and determines it reactivity.
Which factor determines the reactivity of a compound?
total number of electrons
Do valence electrons affect the reactivity of an element?
atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.
What determines the reactive properties of an atom?
the number of elements in the atom The group the element is in on the periodic table (how many valence electrons it has). Metals increase in reactivity from right to left on the periodic table and non metals increase in reactivity from left to right, with the exception of group group 18, which is not reactive, and Hydrogen, which is very reactive.
