table). Atoms are the basic building blocks of ordinary matter. Atoms are made up of particles called protons‚ electrons‚ and neutrons. Protons carry a positive electrical charge‚ electrons carry a negative electrical charge‚ and neutrons carry no electrical charge at all. The protons and neutrons come together in the central part of the atom‚ called the nucleus‚ and the electrons ’orbit’ the nucleus in the electron cloud. An element is a substance that is made entirely from one type of atom. For example

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic

acknowledge the reason atoms react with one another in the first place. Each element has a certain number of valence electrons‚ an example being Sodium having one valence electron. When elements react they are trying to get a full shell of eight valence electrons by either giving away‚ taking in‚ or sharing valence electrons. The best way I can think to describe how atoms decide which method to do is that atoms have their

simulacra‚ thin films of atoms released from everything. From a logical standpoint‚ even without taking modern technology into consideration‚ Lucretius’ theory of Simulacra does not hold up well against scrutiny due to the weak foundational assumptions and contradictive information. Lucretius theory of simulacra is that simulacra is made of physical atoms that are given off everything in existence. This poses the question of why can we not see simulacra? If simulacra is made of atoms‚ then we should be

Ancient Greece Greece The Greek peninsula has been culturally linked with the Aegean Islands‚ and the west coast of Asia Minor since the Neolithic Age. The numerous natural harbors and close-lying islands lead to a unified‚ maritime civilization. However cultural unity did not produce political unity. Mountain ranges and deep valleys separated the peninsula into small economic and political units. Constant feuding between cities and surrounding empires for political power made Greece the sight

Persian rule was very influential in the fields of art and education. It was in this time when Babylon experienced the development of mathematics‚ cosmology‚ and astronomy‚ subjects that were highly regarded. It is also said that Thales and Pythagoras had studied‚ lived‚ and developed their ideas in Babylon during Persian rule (Mark‚ “Babylon”). However‚ the Persian rules abruptly ended with the conquest of Alexander the Great‚ who viewed the city with reverence‚ hereby ordering

model of the atom that helped establish many scientific concepts and also created the foundation for more modern models. His model suggested that atoms are the smallest particle of an element‚ that atoms of different elements have different masses‚ and that they are solid‚ indestructible units - much like a billiard ball .He called his model the " Billiard Ball model" because he thought that atoms looked like billiard balls from pool. Dalton’s Atomic Theory included five main points. Atoms: Make

what an atom is and what its components are. One of these discoverers‚ John Dalton‚ developed the first modern atomic theory. Although much of his theory is still true today‚ one point was disproved by Ernest Rutherford. Dalton’s atomic theory had several parts to it. He believed atoms were indivisible‚ or impossible to break down into smaller particles. Also‚ he said elements are all consisted of atoms and that the atoms of each element are different from each other. All of the atoms of the

If Thales was the first of all the great Greek philosophers‚ Plato must remain the best known of all the Greeks. The original name of this Athenian aristocrat was Aristiclis‚ but in his school days he received the nickname "Platon" (meaning "broad") because of his broad shoulders. Plato was born in Athens‚ Greece to one of the oldest and most distinguished families in the city. He lived with his mother‚ Perictione‚ and his father‚ Ariston (Until Ariston died.) Born in an aristocratic and rich
