2. Ions-
3. Catalyst -
4.Cation-
5.Ductility-

For all 5 right answer I'll mark u as brainllist ​

Answer 1

Answer:

1. An alloy is a homogeneous mixture of two or more metals or a metal and a non-metal.

2. An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

3. A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

4. A positively charged ion, i.e. one that would be attracted to the cathode in electrolysis.

5. Ductility is a mechanical property commonly described as a material's amenability to drawing. In materials science, ductility is defined by the degree to which a material can sustain plastic deformation under tensile stress before failure.

Answer 2

Explanation:

An alloy is a combination of metals or metals combined with one or more other elements.

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule.

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process.

a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis is a cation.

the ability of a material to have its shape changed (as by being drawn out into wire or thread) without losing strength or breaking is ductility
