What can less reactive metals be found as?
Less reactive elements are more likely to be found uncombined, that is as the element rather than as part of a compound. This is usually called being 'found native'. For instance gold mines contain actual pieces of gold, whereas an iron mine usually contains something like rust, which has to be converted by a chemical reaction to obtain the metal.
How reactive is osmium?
Osmium has varying states of reactivity. Its pure state tends be quite reactive and is rarely used unless alloyed. Osmium tetroxide is extremely reactive, whereas osmium dioxide has very little reactivity.
What characteristics of the atomic structure of helium make it so such less reactive the hydrogen?
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
How do psychical and chemical properties of halogens compare with those of the inert gas?
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
What is the least reactive group in the periodic table?
Noble gasses (group 8) are the least reactive elements in the periodic table because they have a full valence shell.The right-most column, Group 8*, or the noble gases, is the least reactive elements in the periodic table.* In newer version of periodic table by IUPAC, its the group 18; whereas it was the 8th A group that noble gases occupied in older version.
What does it mean to say some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.

What is the difference between sodium and aluminum'?
Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.

Why is the arrangement of electrons in an element key to understanding why each element behaves the way it does?
The elements in the periodic table are arranged based on how reactive they are, which is based on how many electrons they have in their outer shell. For example, the elements on the ends are very reactive because on one side the elements have seven electrons and on the other the elements have one. The elements with one electron are trying to get rid of their electron whereas the elements with seven electrons are trying to find another to make their shell complete, as there are eight electrons in the outer shell of an electron shell.

Why does Aluminium occur in a form of a compound whereas gold is found in free state?
This is because metals like gold lie at the bottom in the activity series so they are less reactive and are found in the free state, whereas, metals like aluminium, zinc, etc. are found on the top of the activity series so they are highly reactive and are found in the form of compounds.
Why phosphorus stored in water whereas sodium stored in kerosene?
Because phosphorus is very reactive non metal. It catches fire if exposed to air. To prevent the contact of phosphorus with atmospheric oxygen,it is stored in water. Whereas,sodium is very reactive. It reacts vigorously with oxygen and water. A lot of heat is generated in the reaction. It is, therefore,stored in kerosene
Where is the transuranium elements located on the periodic table?
Transuranium elements are elements that appear after uranium. Elements with atomic number 93 to 103, appear in the actinides whereas elements with atomic number 104 to 118 appear in the 7th period.
