Nitrogen, Oxygen, Flourine, and Chlorine. Bromine and Iodine are both joined together in their own molecule, but Bromine is a liquid and Iodine is a solid. The way i remember these 'diatomic' (they are elements in pairs of two atoms to a molecule) elements is by, NOFClBrI. Sticks in your head and they form an upside down 'L' shape in the Periodic Table.
Two or more atoms joined together are called molecules. These molecules can be composed of the same type of atoms, known as elements, or different types of atoms, forming compounds.
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
Magnesium chloride is composed of one magnesium atom and two chlorine atoms, making a total of three elements that are joined together to form magnesium chloride.
Molecule
It's H2O which means two hydrogen molecules to one oxygenThe elements of Hydrogen and oxygen are chemically joined together to form water. Two atoms of hydrogen and one atom of oxygen are joined together chemically to form one molecule of water.
Elements are those substances which have same constituent particle altogether. Molecules are a group of atoms joined together . Atoms of elements join together to form a molecule.
A group of atoms chemically joined together is called a molecule. Molecules can be made up of two or more atoms of the same or different elements bonded together.
Two or more atoms joined together are called molecules. These molecules can be composed of the same type of atoms, known as elements, or different types of atoms, forming compounds.
A molecule is made of two or more atoms joined together through chemical bonds. These atoms can be the same element or different elements, leading to the formation of various compounds.
Molecules are made of different atoms joined together through chemical bonds.
Molecules are made of more two or more atoms joined together. The atoms can be same or different elements. A single molecule is the smallest piece of matter.
atoms
because they are chemically joined together and it is difficult to separate them
Two or more atoms joined together form a molecule. You can't say compound because you do not specify that the atoms are of different elements. You can have a molecule of oxygen because two or three atoms of oxygen can couple together by themselves, but it is not a compound, it is a molecule of oxygen.
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
In a molecule, atoms are joined together by bonds. When we say bonding, we are referring to these bonds.
Magnesium chloride is composed of one magnesium atom and two chlorine atoms, making a total of three elements that are joined together to form magnesium chloride.
