Question

Match the type of matter to the correct descriptions. Each description may connect to more than one type of matter.
Description
can be represented using chemical symbols
can have subscripts in their chemical formulas
are represented on the periodic table
are always made of two or more atoms
describe helium (He) gas particles

Types of Matter
atoms
elements
molecules
compounds

Answer 1

Here's the matching of types of matter to the correct descriptions:

### Descriptions and their Matches:

1. **can be represented using chemical symbols**
- **Match:** elements, atoms (since each atom has a corresponding symbol)

2. **can have subscripts in their chemical formulas**
- **Match:** molecules, compounds (subscripts indicate the number of atoms in a molecule or compound)

3. **are represented on the periodic table**
- **Match:** elements (elements are listed on the periodic table)

4. **are always made of two or more atoms**
- **Match:** molecules, compounds (both consist of two or more atoms; compounds specifically consist of two or more different elements)

5. **describe helium (He) gas particles**
- **Match:** atoms, elements (helium is an element and exists as single atoms, or He gas, which are individual helium atoms)

### Summary:
- **Atoms:** can be represented using chemical symbols, describe helium (He) gas particles
- **Elements:** can be represented using chemical symbols, are represented on the periodic table, describe helium (He) gas particles
- **Molecules:** can have subscripts in their chemical formulas, are always made of two or more atoms
- **Compounds:** can have subscripts in their chemical formulas, are always made of two or more atoms
