How do you identify elements and compounds?
Elements are defined by the number of protons in a given atom, and the atom is the smallest unit of an element. In contrast, a compound is defined by the identity and organization of multiple atoms, with the smallest unit of a compound being a molecule. Some compounds do contain only one element, such as diatomic gases or graphite.

Giftedness in children could be thought of as ‘expertise in development’.1 They may or may not be currently high achievers and their potential may emerge at any stage in their development.
What makes a compound a compound?
A compound is a group of two or more different atoms chemically bonded together. What makes compounds special is that there are at least two different elements, or types of atoms in the group. All compounds are molecules, but not all molecules are compounds. Carbohydrates and water are molecules because they are made of at least two atoms.
What are the elements that make up the periodic table?
Gold, silver, lithium, strontium, and neon are all elements, as are all of the other items on the periodic table. When elements combine, they form molecules. Simply put, a molecule is a group of two or more atoms chemically bonded together. This includes the carbohydrates you eat, the water you drink, and the oxygen you breathe.
What is a group of atoms called?
Molecules Are Groups of Atoms. While many things in nature do come in their pure elemental form, there are of course many other things that do not. Instead, they are combinations of elements. When elements combine, they form molecules . A molecule is a group of two or more atoms chemically bonded together.

For example, some simple molecules include the oxygen you breathe, which is made of two oxygen atoms, the salt you put on your food, which is made of one sodium atom and one chlorine atom, or the water you drink, which is made of two hydrogen atoms and one oxygen atom.
Is a compound a group of two or more atoms?
Compounds Are Different Elements. Molecules are groups of two or more atoms, but there is a special sub-group of molecules, too. These are compounds, and a compound is a group of two or more different atoms chemically bonded together. The key here is that compounds are made of at least two different elements.
What is everything made of?
Everything on Earth is made of atoms, and sometimes they combine to form new groups of atoms. The sky is the limit when it comes to these combinations, which account for the vast number of things we find in our natural world. Create an account.
Is water a molecule or a compound?
Carbohydrates and water are molecules because they are made of at least two atoms. But they are also compounds because they are made of two different types of atoms as well. The oxygen you breathe is a different story. It's made of two oxygen atoms, so it definitely meets the criteria for being a molecule.
What determines how an atom will interact with other atoms?
These are called the valence electrons and their number determines how the atom will interact with other atoms. The tendency of an atom is to fill or empty its valence shell and it will react with another atom in a manner that depends upon that other atom's specific valence shell configuration. Promoted by DuckDuckGo.
What is the name of the element that can combine to make a compound?
For example, Hydrogen contains only Hydrogen atoms. Different elements combine to make a compound. That means, hydrogen can combine with oxygen to create a compound called 'Water'. A compound is 'impure', that means it contains more than one type of atom. Water compound.
What are the three subatomic particles that make up the atoms of an element?
