1. All metals lose electrons however gold can form aurides. 2. All metals conduct electricity. 3. All metals do metallic bonding. 4. All metals have free electrons. 5. All metals react with fluorine. 6. No metals are gases at RTP, there're either liquid (caesium, gallium, mercury) or solid. 7. Nearly all metals are shiney silver in colour except copper, gold and osmium. 8. All metals are at least fairly good conductors of heat. 9. All metals form atleast 1 compound soluble in water. 10. All metals have atleast 1 full s subshell This is way to broad of a question to possibly get 14, there are many different groups of metals the s block metals which are split into alkali and alkali earth metals, transition metals, poor metals, rare earth metals which are split into lanthanoids and actinoids.
there is no way i can answer this!Some examples of characteristic properties are:Melting PointBoiling PointFreezing PointDensityTemperatureSolubilityMagnetismI hope this helps you!

Non-metals are much more diverse than metals, however, they all have some similar physical properties. Non-metals are not good conductors of heat or electricity. Solids are usually brittle, non-ductile, not shiny, and at least partially transparent or translucent.
Metalloids are elements that have properties of both metals and nonmetals. They are located on the periodic table along the staircase between metals and nonmetals. Examples of metalloids include silicon, germanium, and arsenic.
Some are but the most reactive are also non-metals.
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Metal like Sodium Chloride. Sodium is the Metal and Chloride is the Nonmetal.
Molecular compounds are typically made up of nonmetals. Metals tend to form ionic compounds with nonmetals, whereas nonmetals tend to share electrons with other nonmetals, resulting in the formation of molecular compounds through covalent bonding.
Elements that are classified as non-metals are characterized by a tendency to undergo chemical reactions in which they acquire electrons; this compares to metals which tend to lose electrons. In slightly more technical terms, this means that non-metals are oxidizing agents and metals are reducing agents; when you mix metals and non-metals together, they tend to react with each other, in what is sometimes called a redox reaction (reduction and oxidation). Other than that, non-metals are generally softer (or gaseous) and less shiny than metals are, they generally do not conduct electricity as well as metals do, they do not have the silvery color of metals.
Nonmetals are not necessarily the least electronegative elements, but they generally have higher electronegativity values compared to metals. Within the periodic table, noble gases are typically the least electronegative elements, as they have a complete outer electron shell and have low tendency to attract electrons.
There are at least two possible answers to this question. The two most usual ones are probably: metals, nonmetals, and metalloids; or main group, transition elements, and inner transition elements.
Some elements are metals; others are not. You are familiar with the general physical properties of common metals such as iron, copper, silver and gold. The other metallic elements are those that have similar physical or chemical properties. There are also some other elements that are similar enough, such as antimony, that they considered to be metals by some people. Metals are typically at least somewhat hard, shiny, able to be pressed or hammered into shape without breaking or cracking (unlike glass, for example) and good conductors of electricity and heat.
Nonmetals, such as oxygen or sulfur, are typically gases or brittle solids at room temperature. They have poor conductivity of heat and electricity due to a lack of free electrons to carry the charge.
The Halogens are the most reactive non-metals. However, their reactivity decreases as you go down the group. Most reactive Fluorine>Chlorine>Bromine>Iodine>Astatine Least reactive. However, Astatine is not fully characterised because it is radio-active, and consequently is not found in open(school) labs.
