Lattice parameter of metal A and B are 2 and 4 what will be lattice parameter of alloy AB A20B and A50B?

Indeterminate. If the atoms form a perfectly mixed solution then you might guess 2a+4b where a and b are the fractions of A and B. But if they form a super-lattice where the stacking of the atoms only repeats over a long range (as happens in the many structures of silicon carbide [silicon and carbon are not metals]) then you can get almost anything, with various seemingly unconnected sequences and lattice lengths, even in different directions. For very dilute things like A50B you will get the normal lattice period of A over much of a crystal but with lattice distortions around the occasional B atom. That would cause a broadening of x-ray diffraction patterns.

The lattice structure in a metal is?
A metallic lattice consists of positive ions in a 'sea' of outershell negative electrons which are delocalised and mobile through the metal structure. The lattice is held together by strong forces of attraction between the mobile electrons and the positive ions.
Which one is hardest metal diamond or aluminium or silver or platinum?
Diamond is the hardest substance known - but it is not a metal it is an arrangement of carbon atoms in a lattice.
Although metals and salts have similar lattice structures metals make good materials for electrical wiring Why aren't salts used instead?
Atomic lattices (like graphite) and more specially metal atomic latice behavevery differently to electrons (current) compared with positive metal ions in their latice together with negative anions (called ionic lattice).
Ask us happens at the atomic level when a metal is subjected to pressure such as a blow from a hammer?
The atom remain unchanged but the arrangement of atoms in the lattice is modified.
Why do electrical wires burn out?
Actually when a wire is burnt a layer of oxide of the metal is formed which has a very high lattice energy and so it cannot be broken into constituent ions under ordinary conditions.That's why a burnt metal cannot conduct electricity.
How does adding larger metal atoms to a metal lattice make the metal harder?
No!

How do you solve the lattice metal puzzle?
There are many different types of lattice metal puzzles. Each has lots of different steps before the metal puzzle can be solve there are some that have 22 moves before even getting the first piece out.
Does sodium have an allotrope?
Since sodium is a metal, it does not readily accept covalent bonds with itself. Sodium metal is typically a lattice of metallically bonded elements.
What is the structure of lead metal?
Normally lead metal will have a cubic face centered lattice structure.
The ions in solid sodium chloride are arranged in a structure called an?
metal lattice
How does adding larger metal atoms to a metallic lattice make the metal harder?
so by adding larger atoms to a mettalic lattice would make the atoms not to slide over each other easily
What is the structure of metals?

Why are particles in copper metal are close together?
Electrostatic forces and the shape of the crystal lattice.
Would copper exist as a lattice form or molecules?
It is a solid metal and therefore latice form.
Is NA2O molecular or ionic?
Sodium, being a highly reactive metal, and oxygen being a strong non metal, they form an ionic lattice.
Which one is hardest metal diamond or aluminium or silver or platinum?
Diamond is the hardest substance known - but it is not a metal it is an arrangement of carbon atoms in a lattice.
