What is the difference between metals and metalloids?
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.
What is the meaning of allotrope?
allotropy is a phenomenon where an element exists in different forms having different physical properties and same chemical properties is known as allotropy.
What are Advantages of using cryogenics?
Cryogenic Processing of metals (i.e. metals frozen to low temperatures) show more resistance to wear
why do alkali metals not show plus 2 oxidation state?
why do alkali metels not show +2 oxidation state
Are alkali metals electro-positive?
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.
Do metals nonmetals and metalloids all exhibit allotropy?
yes
What is an allotropy?
An allotropy is a property exhibited by some elements of existing in multiple forms with different atomic structures.
Does chlorine shows allotropy?
No. Chlorine does not exhibit allotropy but it exist as an isotope example Cl 37 and Cl 35.5
Do allotropes form salt?
Allotropy is phenomenon only for chemical elements.
What is meant by the term allotropy?
The term allotropy refers to a chemical property where one element can have similar atoms that can be arranged in different shapes to form different materials. That is why graphite and diamond are made out of carbon but have different forms.

What is meant by allotropy?
Allotropy is a given element exhibiting different physical characteristics. Common allotropes are :- Carbon ; Graphite , Diamond, & Buckminster Fullerenes (footballenes). Oxygen ; Oxygen & Ozone Sulphur ; Yellow, Red and White Phosphorus ; Red and White. Allotropes are formed by different arrangement of the atoms of a given element.
How many are metals?
There are 86 metals.
What types of elements show malleability and ductility?
metals
Which are the metals which show and do not show photoelectric effect?
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).
How could you show that the group 1 elements are metals?
