Two or more elements that are chemically bonded form a molecule of a chemical compound. This is the simple and direct answer to a good basic chemistry question. A molecule. However, if the chemical bond is ionic (like in a salt), it isn't called a molecule, but instead a compound. There are no salt molecules!

A mixture with more than one visible phase?
yes because it has more phases according to their mixture
Why are elements often called the building blocks of matter?
They are the smallest particles of matter. Actually, it's a misconception to say that atoms and molecules are "small particles";rather, they are the tiny electrical forces that can't be seen with the naked eye. Atoms and molecules are not tangible, physical objects-they are forces.
Three main parts of the atmosphere are the?
if you mean chemically its Oxygen 29%ish, Nitrogen 70%ish, 1% argon and other trace elements Or the Thermosphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere, in that order from the earth's surface, but there are more than 3
What type of substance contains more than one kind of element?
anything that is not in the periodic table probably contains more than one kind element. steel, plastic, rubber are all examples
Which planet has more mass than the other planets combined?
Jupiter.
Is an element composed of atoms of two or more compounds chemically combined?
Compounds are composed from elements.
What are composed of 2 or more elements that have been chemically combined?
Two or more elements chemically combined form a compound.
What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
When two or more atoms from different elements join they form?
When two or more atoms from different elements join together chemically they form a compound. The compound can be ionic or covalent/molecular depending on the elements that are combined.
When two or more atoms form different elements join they form?
When two or more atoms from different elements join together chemically they form a compound. The compound can be ionic or covalent/molecular depending on the elements that are combined.
Compounds are made from different atoms of two or more?
Yes, also molecules are like compounds, but they can have 2 or more of the same atom.
Are all elements compounds?
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
Are all elements are compounds?
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
When hydrogen and oxygen are combined how many of these atoms are compounds?
An atom is not a compound. A compound is a pure substance that is composed of atoms of two or more elements chemically combined. The elements hydrogen and oxygen combine to form water, which is a compound. 2H2 + O2 --> 2H2O
Is a substance made of two or more elements chemically combined?
CompoundThis is called a compound. The molecules of compounds usually have different properties than the atoms of the constituent elements.
What describes compound?
they are two or more elements that are chemically combined
Explain the difference between elements and compounds?
An element is composed of only one kind of atom. A compound is composed of two or more elements (kinds of atoms) chemically combined.
