14 properties of metals?
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.
A desciption of a characteristic properties that gives at least three examples?
there is no way i can answer this!Some examples of characteristic properties are:Melting PointBoiling PointFreezing PointDensityTemperatureSolubilityMagnetismI hope this helps you!
Shinny good conductors malleable?
Metal elements such as iron, aluminium and silver.
All flat maps are projections that must distort at least one what properties distance shape size and what else?
DIRECTION
Why do scientist keep tools in the science laboratories?
writ at least 5 physical channges each of a boy and girl
Do all nonmetals have some similar physical properties?
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.
Are nonmetals least reactive?
Some are but the most reactive are also non-metals.
What properties do non metals have in common?
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.
What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Are molecular compounds made up of metals or nonmetals?
Some molecular compounds, such as methyl mercury, contain both metals and nonmetals. Most molecular compounds contain only nonmetals, and all molecular compounds contain at least one nonmetal element.
What comes first the metals or nonmetals?
Metal like Sodium Chloride. Sodium is the Metal and Chloride is the Nonmetal.
Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity?
Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity are non metals. A metal is an element that has luster, is a good conductor of heat and electricity, is malleable, and is ductile
Are non metals least electronegative?
Nonmetals tend to have a higher electronegativity value than metals. Fluorine, a nonmetal, has the highest electronegativity value.
What are the differentiate of elements and metals?
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.
What period in the periodic table contains the largest number of nonmetals?
Period 2, It only contains two metals, making it the least metallic period
A periodic pattern appears in the physical and chemical properties of the elements when they are arranged in order of increasing atomic number?
That there is a periodic repetition of their physical and chemical properties. #RRS
How do metals differ from nonmetals?
Metals usually have characteristic(s) of at least one of the following: luster, shine, malleable, ductile, and conducts electricity. Non metals don't conduct electricity and are usually brittle.
