What is the smallest unit of matter that retains the identity of the substance?
If that substance is an element, the smallest part is the atom which, if broken down further into atomic particles, loses its identity.
Which particles in an atom can increase or decrease in number without changing the identity of the element?
Neutrons
What is the definition of molecule?
Molecules are the smallest particles of a substance.
The smallest particles into which an element may be broken down without changing the identity of the elements are?
Quarks
When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
What is the smallest unit of matter that retains the identity of the substance?
If that substance is an element, the smallest part is the atom which, if broken down further into atomic particles, loses its identity.
What is a pure substance that has all particles the same?
An element.
Which particles in an atom can increase or decrease in number without changing the identity of the element?
Neutrons
What is the definition of molecule?
Molecules are the smallest particles of a substance.
The smallest particles into which an element may be broken down without changing the identity of the elements are?
Quarks
A substance in which all of the building block particles are identical is called?
An element. The particules are atoms.
What is the smallest particle of a substance that has all the particles of a substance?
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.
Why does the number of proton in an atom determine the identity of the element?
Because the protons keep their integrity/identity whilst the electrons act as 'glue' binding all the subatomic particles together.
What is the identity of element of multiplication?
There is no such thing as an "identity of element". The identity element of multiplication, on the other hand, is the number 1.
What is the identity element for multiplication?
An identity element is an element of a set which leaves other elements unchanged when combined with them. For multiplication, the identity element is 1 .
Is smoke a gas a compound or an element?
No, smoke is a substance of very, very tiny solid particles dispersed in air.
Simplest particle of many compounds?
Atoms of the elements are the simplest particles of compounds. The definition of an element is a substance that cannot be broken down into a simpler substance or interconverted.
