Question

Answer the following questions:
1)state the properties of metals
2) state the properties of nonmetals
3) how are metals ions formed? give two examples.
4) how are metal oxides formed? explain with an example
5) how will you show that metal oxide are basic in nature.​

Answer 1

Answer:

1 ) Ans- high melting points.

good conductors of electricity.

good conductors of heat.

high density.

malleable.

ductile.

2) Ans- High ionization energies.

High electronegativities.

Poor thermal conductors.

Poor electrical conductors.

Brittle solids—not malleable or ductile.

Little or no metallic luster.

3) Ans- As an example, iron commonly forms two different ions. ... It can sometimes lose two electrons to form the Fe2+ ion, while at other times it loses three electrons to form the Fe3+ ion. Tin and lead, though members of the p block rather than the d block, also are capable of forming multiple ions

4) Ans- Metal oxides are crystalline solids that contain a metal cation and an oxide anion. They typically react with water to form bases or with acids to form salts. MO + H2O → M(OH)2 (where M = group 2 metal) Thus, these compounds are often called basic oxides.

5) Ans- when metallic oxides react with water they form metallic hydroxides which are basic in nature.to show that these are basic in nature,we should conduct a litmus paper test.in this experiment,we will observe that red litmus turns blue on coming in contact with them. this shows that metallic oxides are basic in nature

Answer 2

Explanation:

Q1.

hardness laster ductily high melting and boiling point density malleability

Q2.

no luster brittleness no density low melting and boiling point

Q3.

metals made kataions

Q4.

metat+ oxygen---------> metal oxides
