What is it called when to atoms combine?

What is it called when to atoms combine?

When different types of atoms combine, the result is called a compound.

What happens when atoms are combined into a large atom?

Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission.

How do atoms combine to form?

When atoms combine by forming covalent bonds, the resulting collection of atoms is called a molecule. We can therefore say that a molecule is the simplest unit of a covalent compound. As we will now see, there are a variety of different ways to represent and draw molecules.

What happens when the same kind of atoms combine?

An element is made up of atoms of one kind only. When these atoms of the same or any kind combine they form molecules. Thus, two Hydrogen atoms combine to form a Hydrogen molecule. Most atoms can also combine with atoms of different kinds to form compounds of molecules.

When two atoms combine to form a molecule energy is released?

Energy is released when the electrons associated with the two hydrogen atoms form a covalent bond. The process releases heat; therefore, it is exothermic. The heat released when one molecule of a compound forms at 298 K is the standard enthalpy change (ΔH°) for the process.

What happens when atoms combine to form bonds?

When atoms combine through chemical bonding, they form compounds—unique structures composed of two or more atoms. In ionic compounds, electrons are completely transferred from one atom to another so that a cation—positively charged ion—and an anion—negatively charged ion—form.

What happens when two atoms combine?

When two or more atoms chemically bond together, they form a molecule. In a covalent bond, electrons are shared between atoms. The bonds between the two hydrogen atoms and the oxygen atom in a molecule of water are covalent bonds. As its name implies, a metallic bond occurs between metallic substances.
