When atoms combine with or break apart from other atoms a what occurs?
Shanda99
When new bonds are formed between atoms, energy is released and this process is known as exothermic process. Similarly when old bonds break, energy from the surrounding is absorbed and is known as endothermic process.

Change in which 1 or more substances combine or break apart to form new substances?
This is a chemical change, also known as a chemical reaction.
When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
The hydrogen bonds break.
How is promethium reactions?
Atomic fission is the process in which large atoms break apart, releasing large amounts of energy and smaller atoms. The smaller atoms are called fission products. The Oak Ridge scientists proved that element 61 was present in fission products of uranium. They named it promethium, after the Greek god Prometheus.
Are ionic bonds hard or soft?
They are hard because the positive and negative charged ions attract eachother. It takes a lot of energy to break these charges apart.
How do atoms respond when they absorb energy?
Depends on the atoms and how they are situated. Examples : in a fired bullet ... they all travel at a high(er) velocity. In a pot of boiling water ... each molecule moves faster until it escapes the pot. in fluorescent material ... the electrons gain energy, and then release it as a glow. In a nuclear plant ... some atoms break apart into 2 or more atoms (fission).
What do atoms do when they combine?
They break apart rearrange and form new molecules.
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
What type of reaction occurs when atom combine to form molecules or when molecules break down into atoms?
Chemical reactions.
What type of reaction occurs when atoms combine to form molecules or when molecules break down into?
These are two forms of a chemical reaction. The first type is called synthesis and the other decomposition.
What would happen if you would break molecules apart?
The subatomic particles of the Atom (neutrons, protons, electrons) are released at high velocity. Some of these particles can strike other atoms and cause them to break apart, releasing large amounts of energy; this is called nuclear fission (atoms fissioning into lighter atoms). A self-sustaining fission reaction where atoms break apart, and cause other atoms to break apart, can be created with many radioactive elements such as Plutonium or Uranium in an event called a Chain Reaction.
What tool do scientists use to break apart the nuclei of atoms?
forceps
What is the source of radio activiy?
Radioactivity is caused by unstable atoms, that break apart.
How does one receive hysteresis?
Hysteresis occurs most commonly in ferromagnetic and ferroelectric materials such as rubber bands and shape-memory alloys. When the material is flexed the atoms often break apart causing hysteresis.
A change in which one or more substances combine or break apart to form a new substances?

What is the change in which one of or more substances combine or break apart to form new substances?
Chemical change
Will graphite break apart with fracture or cleavage?
The awnser is cleavageit will break apart with cleavage because the carbon atoms are not strongly held together and they are formed from thin sheet so they will break off in thin sheets
What type of reaction occur when atoms combine to form molecules or when molecules break down into atom?
Chemical reactions.
