During physical changes what does matter always retain?

During physical changes, matter always retains its chemical composition, which means the atoms and molecules in the substance remain the same before and after the change. This is because physical changes involve rearranging molecules or changing the state of matter without altering the fundamental identity of the substance.


Can hydrogen be broken down smaller by a chemical change?

No. Chemical changes can only result in rearranging representative particles (atoms, molecules, formula units.) They can't break down atoms any farther than, well, atoms.


When atoms gain electrons during chemical changes what change do they acquire?

Atoms have a negative charge when they gain electrons during chemical changes. Atoms are a basic unit of matter, and everything is made of atoms.


Where no new substance is formed and no rearranging of atoms occurs?

It is a physical change


What does not always stay the same and can undergo physical and or chemical changes?

Matter can undergo physical changes, such as changing state from solid to liquid, or chemical changes where new substances are formed. These changes alter the properties of the matter but do not change the fundamental makeup of the atoms and molecules involved.


Which branch of physical science studies the properties of matter and changes in matter?

The branch of physical science studies the properties of matter and changes in matter is known as chemistry. This is a branch which is mainly concerned with atoms and molecules and how they interact.


How do you create matter?

Matter can neither be created or destroyed, only changed into other forms of matter or energy as shown by Einstein's equation: E=MC2 Or, by rearranging the equation: M=E/C2 To create matter you would need to build a device that takes energy and turns it into matter.


What atoms gain electrons during chemical change what change do they acquire?

Atoms have a negative charge when they gain electrons during chemical changes. Atoms are a basic unit of matter, and everything is made of atoms.


What is chemical effect?

Chemical effects refer to changes that occur in a substance due to chemical reactions, such as the formation of new compounds, changes in color or odor, and release of energy. These effects are the result of atoms rearranging themselves in different ways to form new substances.


What term is given to the process of rearranging electrons in a semiconductor by adding atoms of other elements?

Doping is the term used to describe the process of adding atoms of other elements to a semiconductor to alter its electrical properties by rearranging the electrons.


Can fire destroy an atom?

Fire cannot destroy an atom. Fire is a chemical reaction that involves the breaking and rearranging of chemical bonds between atoms, but the atoms themselves remain intact. Atoms can only be destroyed or changed through nuclear reactions, such as fission or fusion.


Why paper is matter?

Paper is matter because it is made up of atoms and molecules, just like all physical materials. These atoms and molecules have mass and occupy space, which are characteristics of matter. Additionally, paper can undergo physical and chemical changes, further demonstrating its classification as matter.
