Everything we see is made up of tiny little parts called atoms. The atoms are made of even smaller parts. These are called protons, electrons and neutrons. They are very different from each other in many ways. One way they are different is their "charge." Protons have a positive (+) charge. Electrons have a negative (-) charge. Neutrons have no charge.
Usually, atoms have the same number of electrons and protons. Then the atom has no charge, it is "neutral." But if you rub things together, electrons can move from one atom to another. Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons. They have a positive charge. When charges are separated like this, it is called static electricity.

What was benjamen franklin's contribution to the atomic theory?
Benjamin Franklin's contribution to the atomic theory was his proposal that electricity was a fundamental force that could be understood through atomic models. He conducted experiments with electricity and proposed the idea of positive and negative charges, which later contributed to the development of the atomic theory.
Is the atomic theory always the model of matter?
No, the atomic theory is not always the model of matter. While the atomic theory is widely used and supported, there are other models, such as the quantum mechanical model, that provide a more detailed understanding of matter at the atomic and subatomic levels. These models build upon the atomic theory but also incorporate additional concepts from quantum mechanics.
What important contribution did Lavoisier make to Dalton's atomic Theory of Matter?
What important contribution did Lavoisier make to Dalton's atomic theory of matter? Lavoisier helped the atomic theory of matter, by stating that matter is not destroyed or created, it just changes form. Located inside the nucleus, has a positive charge, and 1 amu.
Who is credited with being the first European to come up with the atomic theory of matter?
The first European credited with the atomic theory of matter is John Dalton, an English chemist, and physicist. Dalton proposed his atomic theory in the early 19th century, stating that all matter is made up of tiny, indivisible particles called atoms.
What nineteenth century scientist designed the atomic theory of matter?
John Dalton, an English scientist, developed the atomic theory of matter in the early 19th century. His theory proposed that all matter is made up of tiny, indivisible particles called atoms, each with its own unique properties. Dalton's work laid the foundation for modern atomic theory and greatly influenced the field of chemistry.
Whose ideas led to the atomic theory of matter?
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.

What theory explains matter at sub-atomic levels?
That is Quantum Theory.
What theory is that all matter is composed of atoms?
Dalton's Atomic Theory
What theory explains matter at sub atomic levels?
That is Quantum Theory.
What was important about atomic theory?
It disproved Aristotle's four-element theory of matter.
Who posited the Atomic theory of Matter?
John Dalton

The two ancient greek theories of matter were the what theories?
Ancient Greeks had two major theories of matter. These were the Atomic theory of matter and the theory of pangenesis.
