Can a molecule be a single atom?
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not considered single molecules.
Which molecule contains only one atom?
When a substance contains only one type of atom, it is called an element. Each element has a special name and unique properties that are different from all the rest of the elements. All known elements are organized on a chart called the periodic table of elements.
How many atoms can a molecule have?
2 atoms
Molecule: group of two or more atoms held together by chemical bonds. So, minimum 2 atoms are required to form a molecule.
Do molecules have different atoms?
A molecule is made up of atoms bonded together. So, while an atom is its own separate entity, a molecule is what you get when those atoms bond together. These might be the same elements, such as two oxygen atoms bonded together (O2), or it might be different atoms bonded together like water (H2O).
Can a molecule be a compound?
A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
Do atoms contain more than one element?
Elementary | BBC World Service. All elements are made of atoms. There are more than a hundred different atoms, but each element contains only one kind of atom. Atoms are what make one element different from another.
What is the simplest atom it only has one proton and one electron?
element hydrogen
The element hydrogen (H) has the simplest atoms. Most hydrogen atoms have just one proton and one electron. The proton forms the nucleus (the centre of the atom), while the electron orbits around it (Figure 5.5, left).
Do molecules have atoms?
A molecule is a neutral particle, composed of a set number of atoms bonded together. The particle of the substance is the molecule, rather than the atoms that make up the molecule.
Are molecules smaller than atoms?
Atoms are even smaller than molecules. Molecules are made up of atoms. Dust, air, water, people— everything is made of atoms.
How are molecules and atoms similar?
How does molecule differ from an atom?
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.
Can an element be a molecule?
Some elements exist naturally as molecules. For example, hydrogen and oxygen exist as two-atom molecules. Other elements also exist naturally as diatomic molecules—a molecule with only two atoms (Table 5.4.
