Which metals are not lustrous?
Lustre Is An Property Of Metals: Thus All Metals Have Lustre However Lead Being A Metal Is Considered To Be Non Lustrous But Actually Lead Is Bright And Silvery When Freshly Cut But The Surface Rapidly Tarnishes In Air To Produce A Dull Lustre Associated With Lead.
Which non metals are good conductor of electricity?
Non-metals like graphite and doped silicon can conduct electricity due to the presence of free electrons that allow for electron movement. However, most non-metals are poor conductors of electricity as they lack the free electrons needed for conduction.
Is it possible for metal and non metals to form non polar covalent bond?
No, it is not possible for metals and non-metals to form non-polar covalent bonds because non-polar covalent bonds involve the sharing of electrons equally between two non-metal atoms, which have similar electronegativities. However, metals typically have low electronegativities compared to non-metals, resulting in an unequal sharing of electrons and the formation of ionic or polar covalent bonds.
What are three main classifications of elements?
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.
What are the two main metal groups?
The two main metal groups are ferrous metals (contain iron) and non-ferrous metals (do not contain iron). Examples of ferrous metals include steel and cast iron, while examples of non-ferrous metals include aluminum, copper, and lead.

What are two patterns of families science?
The two patterns include metals and non-metals. metals are placed on left and non-metals on right side.
What two elements are likely to react together?
A metal and a non metal. Two non metals. A metal and a metalloid.
What are two major groups of a mineral?
metals and non-metals
What are two types of element?
Metals and non-metals are the two primary categories of elements.
What are the 2 groups that divide the periodic table and their properties?
Metals and non-metals are the two groups. Metal loose electrons. Non metals gain electrons.
What is the mixture of two or more non metals?
mixture of two or more non metal is known as alloy
Which non metals are good conductor of electricity?

What kind of bond will two fluoride ions create?
Ionic bonds are between metal and non-metal. Covalent bonds are between non-metals. Two Flouride ions would both be non-metals.
What is a non-metallic?
The elements on a Periodic Table are sorted into two different categories - 'metals' and 'non-metals', so there isn't actually something called a 'non-metal metal'. Examples of non-metals include oxygen, carbon and nitrogen.
Is a non metal?
The elements on a Periodic Table are sorted into two different categories - 'metals' and 'non-metals', so there isn't actually something called a 'non-metal metal'. Examples of non-metals include oxygen, carbon and nitrogen.
What are the two very reactive non metals?
They are: fluorine and oxygen.
