Yes, they may.
Common examples are CO2 and H20.
There are also seven diatomic molecules (molecules with only one type of element in them).
They are: N2, F2, H2, Cl2, I2, Br2, F2
yes
Oxygen is an element in its own right, so it only contains one element: oxygen.
All atoms of the same element contain the same number of protons in the nucleus. This is what defines the element and gives it its unique characteristics.
Atoms of the same element must contain the same number of protons. This is because of the positive charge they provide.
Atoms of the same element are alike in terms of their number of protons, which determines the element. However, atoms of the same element can differ in the number of neutrons they contain, leading to different isotopes of that element.
yes
The prefix for seven atoms of the same element is "hepta-". So a molecule with seven atoms of the same element would be described as "heptatomic".
No, the oxygen molecule is made up of two atoms of the same element, oxygen.
Molecule
Molecule
No, the atoms in a molecule do not need to be all different. Molecules can contain multiple atoms of the same element or different elements bonded together. The arrangement and types of atoms in a molecule determine its properties.
Oxygen is an element in its own right, so it only contains one element: oxygen.
protons
All atoms of the same element contain the same number of protons in the nucleus. This is what defines the element and gives it its unique characteristics.
Atoms of the same element must contain the same number of protons. This is because of the positive charge they provide.
When two atoms of the same element come together, they form a molecule of that element. For example, when two oxygen atoms come together, they form a molecule of oxygen (O2).
Atoms of the same element are alike in terms of their number of protons, which determines the element. However, atoms of the same element can differ in the number of neutrons they contain, leading to different isotopes of that element.
