Do electrons in the lowest energy level of an atom that determine how that atom reacts?
Electrons in the outer shell, also known as valance electrons, determine how an atom will react. To be more precise I should add that there are transition state elements whose reactivity is also influenced by some of the inner electrons as well.
Which part of an atom determines how it will react with other atoms?
valence electrons
Electrons have diiferent amounts of energy?
The higher the orbital an electron has the higher its energy and the more likely it is to react.
If the outer energy level of an atom is filled with electrons will it react?
Not very well. All of the gases on the right side of the periodic table of elements have full electron outer rings
What type of gas is radon?
It is a Noble Gas from group 18. It is a noble gas since its outer energy level is full and thus does not react to obtain a full set of electrons.

The number of electrons determines what of an element?
The number of loosely held electrons determines the reactivity of an element. Other elements attract electrons and will react also.
Which part of an atom determines how it will react with other atoms?
valence electrons
How many electrons does neon have in the third energy level?
Neon's complete electron configuration is: 1s22s22p6 Therefore, normally, neon does not have any electrons in its third energy level. As you can see, neon is a noble gas with 8 electrons in its valance shell, and is therefore chemically stable and is unlikely to react.
Describe the type of electron configuration that makes an atom stable and not likely to react?
When the highest occupied energy level of an atom is filled with electrons, the atom is stable and not likely to react.
What part of the atom determines how it will react with other atoms?
These particles are the electrons.
What would react more vigorously with water strontium or calcium?
Strontium. They both have two electrons in their outermost energy level, however since the electrons are farther from the nucleus in Strontium than in Calcium, Strontium is more readily able to shed these two electrons to achieve a more stable state with it's outermost energy level being complete (with 8 electrons).
What determines whether or not an atom will react with other atoms?
depends on the charges, either negative or positive
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
How do the number of valence electrons affect how likely a substance is to react with another substance?
The number of valence electrons is the number of electrons in the outer energy ring of an atom. The most electrons the first energy level of any atom can hold is two. The rest is 8. If the outer energy level is full, the atom will be less reactive because it cannot add any more electrons to it's current outermost energy level. If it only needs one or two more electrons to fill it's last energy level or if it only has one or two in it's last energy level, it will be more reactive, because it only needs to gain a few or lose a few to be full.
What is meant by neutral gases?
Chemically, a neutral gas is one that is stable (meaning it has 8 valence electrons in its outer level already and does not need to react to achieve these 8 electrons). These gases are also called Noble gases. Helium is considered a neutral gas because it only has one energy level and can only hold 2 electrons (Remember that the goal of elements is to achieve stability, which is why they react. An element is stable when it has 8 electrons in the outer level).
Why do elements in group 18 rarely react with other elements?
Elements in Group 18 already have an octet of electrons, which is a full outer shell of 8 electrons. An octet of electrons makes the element stable, so it does not need to react with any other elements to gain or lose electrons.
