The postulates of John Dalton:
1. All matter is made up of atoms. These are the ultimate particles, and are indivisible and indestructible.
2. All atoms of a given element are identical, both in weight and in chemical properties.
3. Atoms of different elements have different weights and different chemical properties.
4. Atoms of different elements can combine in simple whole numbers to form compounds.
5. When a compound is decomposed, the recovered atoms are unchanged and can form the same or new compounds.

Who Developed the 5 postulates of the atomic theory?
The 5 postulates of the atomic theory were developed by John Dalton in the early 19th century. Dalton's theory proposed that all matter is composed of small, indivisible particles called atoms, and that chemical reactions involve the rearrangement of these atoms.
Explain Pressure using the particle theory of matter?
Matter is anything that has mass and can take up space.The Particle Theory of Matter:1. Matter is made up of tiny particles (Atoms & Molecules)2. Particles of Matter are in constant motion.3. Particles of Matter are held together by very strong electric forces4. There are empty spaces between the particles of matter that are very large compared to the particles themselves.5. Each substance has unique particles that are different from the particles of other substances6. Temperature affects the speed of the particles. The higher the temperature, the faster the speed of the particles
How many phases of matter are there (apex)?
There are typically four fundamental phases of matter: solid, liquid, gas, and plasma. Each phase is characterized by the arrangement and movement of particles.
An ion with 5 protons and 6 neutrons has an atomic number of?
When considering the atomic number, the only information that we need is the number of protons. To know if the particle is an ion, has more or less electrons, how many neutrons, etc - will not change the atomic number. The atomic number is the same as the number of protons, so in this case, the atomic number of an atom (or ion, doesn't matter) with 5 protons is 5.
As of the 1990's scientist have proved the existence of how many states of matter?
As of the 1990s, scientists have proven the existence of five states of matter: solid, liquid, gas, plasma, and Bose-Einstein condensate.

What is a theory in science for kids?
The particle theory is a good theory that's sort of simple to understand. The particle theory consists of five parts. 1) All matter is made up of small particles 2) The particles are attracted to each other. 3) Particles are always moving. 4)When heated, particles move faster and move farther apart. 5) There are spaces between each particle.

What are the six important points to particle theory of matter?
1.All matter is made up of particles. 2.All particles have spaces between them. 3.Particles are always in motion. 4.Particles have attraction forces. 5.Temperature effects the speed in which particles move. 6.All particles of one substance are identical

What are 4 main points of the particle theory?
5 major points of the particle theoryAll matter is made up of extremely tiny particlesEach pure substance has its own kind of particle, different from the particles of other pure substances.Particles attract each otherParticles are in constant motionParticles at a higher temperature are moving faster than particles at a lower temperature.
Is cell or particle smaller?
When you consider the composition of living and non living things, both can be broken down into what comprises them. If one considers non-living matter, then "particle" may be used to describe the smallest unit. As knowledge advances, a "particle" by definition has evolved i.e., quarks being the smallest "particle" of an atom whereas for years it was thought that the atom was the smallest unit of matter. Conversely, the cell is considered the smallest unit of organic (living) matter The only major difference between them is that a cell is the smallest particle of a living object and a molecule (made up of atoms) is the smallest unit of a nonliving object.
5 levels that euclid used in organizing geometry?

What subsystems make up the universe?
It is theorized that dark matter makes up 80 percent of the universe. Another theory is that 68 percent of the universe is dark energy, 27 percent is dark matter, and 5 percent is baryonic matter.
What are the 5 major problems with the Big Bang theory?
The five major problems with the Big Bang theory are: 1) The horizon problem, 2) The flatness problem, 3) The magnetic monopole problem, 4) The dark matter problem, and 5) The dark energy problem.
What is the acceleration of a particle if mass of the particle is 2 kg and force applied on it is 5 N?
2.5N/kg or 2.5m/s2.
