Neon has completely filled orbitals / energy levels. It has 8 valence electrons and has stable electronic configuration. Hence it is chemically inert and generally donot form compounds under normal conditions.
At the top of a chemical diagram, you would typically find chemicals that are less reactive or inert, such as noble gases like helium, neon, and argon. These elements have full outer electron shells and tend not to form compounds with other elements.
Colored ions are normally associated with the transition metals, which aren't actually a "group" in the usual chemical sense of the word. Also, they don't have to be in aqueous solutions.
Nonmetals burning in oxygen form covalent type compounds, as compared to metals which form ionic compounds.
Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.
The hanging wall of a normal fault would be expected to form the floor of a valley.
No, not likely and rather unknown to do so
No. Two metals or more will form a mixture called an alloy.
Carbon normally forms four covalent bonds in its compounds, not ionic bonds.
No, ionic compounds typically form between a metal and a nonmetal. When two nonmetals combine, they are more likely to form covalent compounds, where electrons are shared between atoms rather than transferred.

Yes, astatine can form covalent compounds with sodium, although it is more likely to form ionic compounds with metals due to its position in the halogen group of the periodic table. Astatine's ability to form covalent compounds would depend on the specific conditions and other elements involved in the reaction.
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
Sodium phosphates are ionic compounds.
Ionic bonds are chemical bonds by positive ionic charge(normally hydrogen , metals +) and negative ionic charge(chlorine ,sulphur etc ) that bind to form compounds.
