Compounds are held together by chemical bonds or links between atoms. Such links are known to arise from the deployment of the electrons of the outer shells of atoms, the so-called valence shells.

Are compound substances joined together?
A compound contains atoms of different elements , chemically joined together. Compounds form in chemical reactions, and you need other chemical reactions to separate a compound into its elements.
What is it called when compounds combine?
The combination of two or more elements to form one compound is called a combination reaction. In other words, when two or more elements or compounds react so as to form one single compound, then the chemical reaction that takes place is called a combination reaction.
What keeps compounds together?
Chemical bonds (ionic and covalent bonds) hold compounded atoms together. This attraction is an electromagnetic event which envelops the atoms and causes them to stick together. When atoms transfer electrons to other atoms, they make ionic bonds.
How do compounds combine?
A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons.
What molecules are held together?
The atoms in most molecules are held together by strong attractive forces called chemical bonds. These bonds are formed through the interaction of valence electrons of the combining atoms. In addition to the very strong forces within a molecule, there are weaker forces acting between molecules.
Why do elements combine to form compounds?
The force that holds together the atoms in a compound; chemical bonding occurs because atoms of an a element become more stable by losing, gaining, and sharing electrons. ... Why do most elements tend to form compounds. Because they are unstable and can share electrons in their outer energy levels.
Can compounds be separated?
Compounds can be made or separated based on chemical properties, or by undergoing chemical changes. A chemical change, sometimes called a chemical reaction, is one in which a given substance becomes a new substance or substances with different properties and different composition.
How do elements react with each other?
Atoms react with each other to achieve an octet in their valence shell. Atoms complete their octets by sharing, accepting or donating electrons.
What holds ionic compounds together?
Ionic Bonds
Oppositely charged particles attract each other. This attractive force is often referred to as an electrostatic force. An ionic bond is the electrostatic force that holds ions together in an ionic compound.
How are molecules connected to each other?
Molecules are held together by either covalent bonding or ionic bonding. Several types of non-metal elements exist only as molecules in the environment. ... A molecule of a compound is made out of two or more elements. A homonuclear molecule is made out of two or more atoms of a single element.
How are covalent compounds held together?
A covalent bond happens when the positive nuclei from two different atoms are held together by their common attraction for the shared pair of electrons held between them. Covalent bonds are strong bonds. Atoms that share pairs of electrons form molecules.
How atoms are held together to form substances?
The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Most covalent compounds consist of molecules, groups of atoms in which one or more pairs of electrons are shared by at least two atoms to form a covalent bond.
What atoms are bonded together?
Explanation: Molecules are formed from two or more atoms which are bonded together. Some molecules have covalent bonds, and others ionic. Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons.
How do elements combine to form compounds quizlet?
When two or more elements combine chemically, they form a new substance. Water and it is made up of two elements : hydrogen and oxygen. In water two hydrogen atoms bond with one oxygen atom.
