a neutral atom will have equal amounts of protons and electrons. This number can change as the atom is oxidized or reduced in chemical reactions

What structurally different between an atom and an ion?
Atoms are neutral species containing protons and neutrons in the nucleus and electrons in the orbitals (or shells). Ions are formed when an atom gains or loses electrons. If an atom gains electrons, then negatively charged ions called anions are formed. If an atom loses electrons, then positively charged ions called cations are formed.
Is lithium an isotope ion or neutral atom?
Lithium is two of these but at the same time neither. It's an element. It is best described as an element, a type of atom with unique properties. If the number of neutrons varied, the multiple lithium atoms would be called isotopes. As for neutral vs. ion, if the number of protons is equal to the number of electrons, it is neutral. If it is not, it is an ion, specifically anion (less protons) or cation (more protons). It will always be a neutral atom or ion. It will always be an isotope, but only called so when in a group of lithium atoms with various numbers of neutrons.
What makes radioactive material unstable?
Radioactive material is unstable because it "wants" to change the configuration of the nucleus to one that is more stable. This is a result in an inbalance of the ratio of protons vs neutrons, said ratio being different for each isotope.
What is the general trend that you observe from a graph that plots atomic number vs atomic mass?
Atomic mass generally increasing with atomic number, although there are a few exceptions.
Where are 3 known military hot spots?
Three major hotspots are the two Koreas, a lot of the Middle East, and Greece vs Turkey
What do atoms have a certain number of?
This is a tricky question because of the way it is phrased. Atoms are the most fundamental unit of stable matter and are composed of varying amounts of protons, neutrons and electrons. In neutral atoms, there are as many positively-charged protons in the nucleus as there are negatively-charged electrons. An imbalance between the number of protons and electrons results in a charged ion. The charge is determined by how many more protons (for positively-charged cations) there are than electrons or for how many more electrons (for negatively-charged anions) there are than protons. Neutrons, found in the atom's nucleus, are present in equal or greater quantity than are protons but the relationship between their number and the number of protons is not fixed. The identity of the atom (hydrogen vs. chlorine vs. carbon, etc...) is determined solely by the number of protons present in the nucleus.From all this can you answer your question?

What subatomic particle determines which element it is?
The number of protons in an atom determines which element it is (i.e Silver-47 protons vs. Gold-79 protons)
What is the atomic mass the weighted average of?
It's the averaged weight of all of the known isotopes of an element. Elements have versions of itself that have the same number of protons and electrons, but different number of neutrons. Since protons and neutrons have a mass of 1 amu (atomic mass unit), you change the neutron number, you change the mass . . . even though the element is still the same. Ex: Carbon 14 and Carbon 12 are isotopes of carbon. Both carbon elements, but they each have a different number of neutrons (8 vs 6), so they have different masses.

What are the difference between ions and free radicals?
Polyatomic and molecular ions are often formed by the combination of elemental ions such as H+ with neutral molecules or by the loss of such elemental ions from neutral molecules. Many of these processes are acid-base reactions, as first theorized by German scientist Lauren Gaither. A radical ion is a free radical species that carries a charge. Radical ions are encountered in organic chemistry as reactive intermediates. For more details, check the link in wikipedia to the left of this column.An ion is an electrically charged atom or radical; it can have either a positive or negative charge, depending upon whether it has lost or gained electrons. A radical is a small group of atoms, such as the nitrate radical composed of one nitrogen and three oxygen atoms. When a compound such as potassium nitrate is dissolved in water, you then get the potassium ion, with a charge of plus one, and the nitrate ion with a charge of minus one. But when the compound is in solid form, it is not ionized and the radical is not an ion.Other version,, An atom or group of atoms having at least one unpaired electron or vacant valency is a radical, there are two types of radicals 1- charged radical or ion 2- free radical as one chlorine atom.
What can you determine about an about an element if you only know its group number on the periodic table?
how many electrons it has in its valence shell usually also some of the characteristics... eg. alkali metals vs. noble gases etc.
How do atoms of oxygen and hydrogen differ?
A hydrogen atom is made from one proton and one electron. An oxygen atom has 8 protons and 8 electrons. Hence their "Atomic Numbers" are "1" for hydrogen and "8" for oxygen. However their "Atomic Weights" are 1 for hydrogen and approximately 16 for oxygen because, in a normal atmosphere, hydrogen exists as a gas cloud of single atoms whereas oxygen exists as a gas cloud consisting of pairs of atoms.
