The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom. The number of the various subatomic particles is the only thing that varies. Scientists now recognize that there are many subatomic particles (this really makes physicists salivate). But in order to be successful in chemistry, you really only need to be concerned with the three major subatomic particles: Protons Neutrons Electrons

What subatomic particles make up the atom?
protons, neutrons and electrons are the main subatomic particles of the atom. There are the same number of protons as electrons, which is equal to the atomic number. The number of neutrons may vary according to the isotope of the element.
What are two physical properties that can vary even when the substance with these properties does not change?
i think Buoyancy and Density are two physical properties that can vary even when the substance with these properties doesn't change.
How do physical properties of the parts a of a pencil affect how the pencil is used?
The physical properties of carbon vary widely with the allotropic form.
How does upthrust vary liquid of different densities?
if a substance has more particles in a smaller space (higher density), then the substance can be less easily displaced and has a higher upthrust
What does sound front mean at obx?
,This is how we classify the sound front properties that we manageSoundside:These homes are located West of Highway 158 from Southern Shores to Nags Head and West of Highway 12 from Southern Shores to Corolla. The distance to the Sound and views vary. Homes may not have direct access to the Sound.Soundfront:These properties front the Sound with no homes or lots in between. The distance to the sound, access to the sound and the view vary. Sunsets can be gorgeous!

What subatomic particles will vary in different isotopes of an element neutrons protons electrons or valence shells?
The number of neutrons is variable.
Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.

i think Buoyancy and Density are two physical properties that can vary even when the substance with these properties doesn't change.
Which of the following statements most closely describes Democritus's ideas about matter?
Democritus believed that matter was made up of tiny, indivisible particles called atoms. These atoms were eternal and unchanging. Democritus also proposed that different physical properties and interactions among atoms resulted in the variety of substances we observe in the world.
Why do the properties of a mixture vary?
because it can
Do the properties of a mixture vary?
because it can
What subatomic particles can differ between neutral atoms of the same element?
The subatomic particle that makes atoms of different elements different from each other is the proton. This is given as the atomic number of the element on the periodic table.
How do the properties of the states of matter vary?
Density does not vary with the state of the matter in a substance.
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
Why do adaptations vary among species?
Adaptations vary among species for quite a few reasons. One reason that adaptations vary is because the environments are different.
Which two subatomic particles are present in equal number in every atom of the same?
In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.
