Metallic oxides are basic in nature, because when metallic oxide dissolves in water it forms corresponding base, which turns red litmus to blue.Those metallic oxide which dissolve in water are known as alkali, while those which do not dissolve in water are known as base
Metals react with acids to form H2. Metalloids also show this type of reactions.
Metals have five main properties: luster (shine), malleability (ability to be hammered into thin sheets), ductility (ability to be stretched into wires), conductivity (ability to conduct heat and electricity), and durability (resistance to wear and tear).
Yes, alkali metals are more reactive than transition metals. This is because alkali metals have low ionization energies and readily lose their outermost electron to form positive ions, whereas transition metals have higher ionization energies and show a more variable reactivity depending on the particular metal and conditions.
Beryllium oxide (BeO) is amphoteric, meaning it can act as both an acid and a base depending on the reaction it is involved in. In general, BeO tends to exhibit more basic characteristics in reactions, but it can also exhibit acidic properties in certain situations.
Hydrogen is not exactly a metal, but has a bonding charge of +1, meaning that it will only bond with materials with negative values. Usually only metals have positive bonding properties, and non-metals the negative.See:Is_hydrogen_a_metal_nonmetal_or_metalloidFor further details.

oxygen and fluorine
Metal oxides are chemical compounds containing a metal and oxygen; the are generally solids.They are formed by reaction with oxygen from the air.Oxides of more electropositive elements tend to be basic. They are called basic anhydrides; adding water, they may form basic hydroxides. For example, sodium oxide is basic; when hydrated, it forms sodium hydroxide.Oxides of more electronegative elements tend to be acidic. They are called acid anhydrides; adding water, they form oxoacids. For example, dichlorine heptoxide is acid; perchloric acid is a more hydrated form.Some oxides can act as both acid and base at different times. They are amphoteric. An example is aluminium oxide. Some oxides do not show behavior as either acid or base.The oxides of the chemical elements in their highest oxidation state are predictable and the chemical formula can be derived from the number of valence electrons for that element. Even the chemical formula of O4, tetraoxygen, is predictable as a group 16 element. One exception is copper for which the highest oxidation state oxide is copper(II) oxide and not copper(I) oxide. Another exception is fluorine that does not exist as expected as F2O7 but as OF2.[1] Since F is more electronegative than O, OF2 does not represent an oxide of fluorine, but instead represents a fluoride of oxygen. Phosphorus pentoxide, the third exception is not properly represented by the chemical formula P2O5 but by P4O10.

Yes they are!even though they are very soft, reactive and not as widely used as much as transition metals eg. in construction they still have other metallic properties, such as metallic bonding.Yes all alkali metals are metals.

Metals are the pure substances by and show only characteristic properties of metals while a metalloid is an element which show some properties of metals and some properties of non metals as Aluminium, Zinc and Tin.
Mercury oxides are: HgO and Hg2O.

All metals will emit a photoelectric effect. However, alkali metals do so in the visible light spectrum, while other metals do so in near-ultraviolet light.The alkali metals are: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr).
