In what type of ratios do atoms combine to form compounds
1 answer:
Answer: whole number ratios
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water
Thus the ratio of hydrogen and oxygen is 2: 1 and is a whole number ratio.

Answer : % ionic character is 0.20%
Bonding between the two metals will be purely metallic.
Explanation: For the calculation of % ionic character, we use the formula
where &
are the Pauling's electronegativities.
The table attached has the values of electronegativities, by taking the values of Al and Mn from there,
Putting the values in the electronegativity formula, we get
= 0.20%
Now, there are 3 types of inter atomic bonding
1) Ionic Bonding: It refers to the chemical bond in which there is complete transfer of valence electrons between atoms
2) Covalent Bonding: It refers to the chemical bond involving the sharing of electron pairs between 2 atoms.
3) Metallic Bonding: It refers to the chemical bond in which there is an electrostatic force between the positively charged metal ions and delocalised electrons.
In compound, the % ionic character is minimal that is
0.20% and there are two metal ions present, therefore this compound will have metallic bonding.
