John Dalton-English chemist that proposed first atomic theory in 1803. :
1. All elements are composed of indivisible particles.
2. Atoms of the same element are exactly alike.
3. Atoms of different elements are different.
4. Compounds are formed by joining atoms of two or more elements.

What did Dalton's atomic theory state?
The smallest unit of matter is the atom. FMOT @DameDash_DatGuy was here
Relative atomic masses are measured in?
Atomic mass is measured in a unit called an "atomic mass unit". This unit is defined as 1/12 of the mass of a carbon-12 atom at ground state.An atomic mass unit is approximately 1.66053886 x 10-27 kg.Atomic mass is measured in atomic mass units (amu) and Daltons.
What is the speed at which molecules or atoms move dependent on temperature and state of matter?
The speed at which molecules or atoms move is dependent on temperature and state of matter. In general, higher temperatures result in faster molecular or atomic movement, while different states of matter (solid, liquid, gas) have different average speeds of molecular motion due to differences in intermolecular forces.
What is the chemical formula for plasma?
plasma is a type of sub atomic particles similar to a gas and sometimes called the fourth state of matter. However all other forms of matter are atomic while plasma is a floating cloud of ionised particles and charged particles like protons and electrons.
Did Dalton's atomic theory state that atoms of different elements combine in simple whole-number ratios can form compounds?
Yes, Dalton's atomic theory included the idea that atoms of different elements can combine in simple whole-number ratios to form compounds. This concept helped explain the law of definite proportions.
Did Dalton's Atomic Theory state that matter is mostly empty space?
No, Dalton's Atomic Theory did not specifically state that matter is mostly empty space. Instead, it proposed that matter is composed of indivisible particles called atoms, which are the building blocks of all substances.
The state of matter of the interior of the sun and other stars?
The state of matter is mostly gas and plasma (free moving atomic parts).
Where does the fourth state of matter exist?
The fourth state of matter is plasma, which is matter that is heated to such a high temperature that it no longer maintains its atomic structure, and becomes a mixture of atomic nuclei and electrons. This exists in fires, and in the sun, and in other very hot places.
What does daltons fourth postulate state?
Dalton's fourth postulate states that atoms of different elements have different weights. This idea laid the foundation for the concept of atomic mass and helped to distinguish between different elements based on their atomic weights.
What are four properties of elements?
Examples: atomic number, atomic weight, density, state of matter, electrical conductivity, etc.
What is a gas like state of matter consisting of free electrons and atomic nuclei?
Plasma is a gas-like state of matter consisting of free electrons and atomic nuclei. Plasma is often considered the fourth state of matter, in addition to solid, liquid, and gas. It is commonly found in stars and lightning.
What can an element's atomic number tell you about its state of matter?
An element's atomic number tells you the number of protons in the nucleus of its atoms. This, in turn, can help predict its state of matter at room temperature. Elements with low atomic numbers are typically gases, while those with higher atomic numbers are solids or liquids.
What did Aristotle's atomic theory state?
Aristotles theory stated that all substances were built from 4 elements, earth, air, fire, and water
What is the particle theory of matter for water boiling?
The particle theory of matter states that all matter is made up of tiny particles. In the case of water boiling, as heat is applied, the particles gain energy and move faster, eventually breaking free from their liquid state and becoming a gas.
What matter is involved inthe big bang theory?
All matter. All the matter that exists emerged from the primordial cosmological state that we call the 'Big Bang'.
What do the proponents of the hydraulic theory for the origin of the state argue?
The proponents of the hydraulic theory for the origin of the state argue that no matter how often energy is conserved or reserved there is a finite amount located in the universe.
What is the state of matter is compose of electrically charge of atomic particles that glow as if burning?
that would be plasma. Plasma is the unsung 4th state element.
