Valence electrons. They determine an element's reactivity. The more of them you have, the more balanced the element is. If you don't have enough, then your element will try to combine with another element. This is because it needs more. If the element has all the electrons it needs it will not react. hope I helped.
Bonds. To be specific, there are two types of bonds between atoms. If you are referring to atoms of elements, this answer is relevant. If not, I am not sure what you are talking about.
The two types of bonds are ionic and covalent. An ionic bond is an electrostatic attraction that exists between two charged atoms, a.k.a, ions. An example would be the positively charged Na ion to a negatively charged Cl.
A covalent bond is a sharing of electrons between two atoms to sustain a bond. This is evident in the bonding of CH2. The carbon shares the electrons of the hydrogens to fill its octet; in return, the carbon fills each of the hydrogens' octets.
This is the chemical bond. It may be electrostatic as in an ionic compound or due to sharing of electrons. Note that the underlying reason for tye sharing - the foramtion of a a lower energy level is due tio the quantum nature of the electron reacting to anthe electrostatic field.
Elements are held together in compounds by the electrostatic force of attraction produced by their bond energy.
Photonic energy. The bonds made in atoms are created by the electromagnetic field, which communicates via the photon.
Ionic
ions
compound is when two or more elements combine chemically
Mixtures
Compounds are formed when elements of matter are chemically combined.
Because the elements in the air arent bonded chemically, they are just literally mix together.
Two or more substances mixed together but not chemically combined form a mixture.
Three elements chemically bonded together would form a compound.
When elements chemically bond together a new chemical is produced
Two or more elements that are chemically joined together is a compound, I think.
compounds
A combination of elements is a process of chemically bonding two or more elements together.
In a compound the component elements are chemically bonded together in a fixed ratio. In a homogeneous mixture the components are not chemically bonded together and the ratio can vary.In a compound the component elements are chemically bonded together in a fixed ratio.In a homogeneous mixture the components are not chemically bonded together and the ratio can be varied.

2 different Elements chemically bonded together is called a Compound.
They form a compound.
You probably mean the molecules formed of atoms in a compound.
It is actually the egg and milk in the pancake batter that holds it together. The milks lactose reacts chemically with the flour and many other ingredients and creates gluten, which hardens the pancake batter and holds it together.
