Question

When two or more elements bond together in specific proportions, _____ is formed. a compound an ion a metal an atom

Answer 1

Your answer is A: compound

Answer 2

Answer: a compound

Step-by-step 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
`Cu`

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

Ion is a specie formed when a neutral atom gains or lose electrons.
`Na^+`

Metal is an element which lose electrons to attain stability. Example:
`Na`

Atom is the smallest unit of matter which is composed of electrons, protons and neutrons.

Thus when two or more elements bond together in specific proportions, a compound is formed.
