Atoms with full octets form stable elements
When you talk about how stable an atom is, you're reffering to the orbitals. If the electron orbitals are all filled, it is said to be stable. If the outer electron orbital is missing some electrons or has too many electrons, it will be more reactive because it wants to achieve that octet of electrons.

False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Conducts heat and electricity very poorly.
They are both properties of materials that do not change and can be used to identify those materials.
The transition elements are metals. As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
Elements with properties of both metals and nonmetals are called metalloids. They are located (rather conveniently) on the "stairstep" on the Periodic Table that separates metals and nonmetals. The metalloids are as follows:SiliconGermaniumArsenicAntimonyTelluriumScientists also suspect polonium is a metalloid, but they can't be sure as polonium is hard to test (it's very radioactive!).

Metalloids
Different names, different elements, different properties.
No. Noble gasses are elements that rarely, if ever form chemical bonds. The elements with both metallic and nonmetallic properties are the metalloids.
Metalloids Metalloids have properties of both metals and non-metals.

Yes, metalloids are elements that have properties of both metals and nonmetals.
Yes, atoms of copper and iron can generally form stable bonds with transition elements. Copper and iron are both transition elements themselves and can form stable bonds with other transition elements. The stability of the bonds will depend on factors such as the electronegativity and bonding properties of the specific elements involved.
The act of bonding repositions the electrons, which changes the base properties of the united molecule. It is for this reason, for example, that oxygen O2 has different properties than ozone O3 even though both compounds only have the element of oxygen.
Conducts heat and electricity very poorly.
