Atom

An atom is contained of a nucleus holding positively charged protons and neutrally charged neutrons. Surrounding the nucleus of an atom are negatively charged electrons. In a neutral atom, the number of electrons and protons are the same. However, the solidity of an atom, is the tendency for the atom to gain or lose electrons, is directly proportional to the number of electrons located on the valence of the atom, the outermost part of the shell. The stability of the electrons determines the physical

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons. There are many Scientist that contributed in the investigation of the atom which are: 1- John Dalton

Do you ever wonder what happens during a chemical reaction? Well, scientist have figured it out. During a chemical reaction atoms rearrange and bonds in different ways. Document three talks about how atoms rearrange to forms new substances in a chemical reaction. The example they used was table salt. Table salt is made of sodium and chlorine. Sodium and chlorine are both harmful substances to humans but, when a chemical reaction happens the sodium and chlorine forms a substance that we put in most

The atom, a constituent particle of a molecule, affects every aspect of life. The theory of the atom is a phenomenon that has occupied the minds of many scientists, who implemented their knowledge and wisdom into experiments. The Ancient Greeks were the first known to discover the existence of the atom. Throughout history the definition of an atom has been changed, added to, and reconfigured, to what we know today. Democritus was the first who suggested the mere existence of the atom. Democritus

Atoms in Electrons “Energy levels in Atoms exist all over the world. Some atoms consist of protons and neutrons making up a nucleus; they are surrounded by electrons. Rutherford made designs and conclusions to develop his nuclear atomic model. Although Rutherford’s model couldn’t explain other properties of elements, such as why metals or compounds of metals give off colors when the flame is heated” (Wilbraham et al 136). John Dalton. (Early nineteenth century) He combined an idea of elements with

(or technically smallest) discoveries of all time: the atom. The long process of solving the mysteries of matter has involved numerous scientists and their experiments, which have ushered in modern knowledge of the subject and countless innovations in science using the knowledge of matter 's properties. The atom makes up nearly everything humankind knows of; therefore, it has significant effect on everything people make. The discovery of the atom by John Dalton and the discovery of the electron by

An atom is the smallest particle of a chemical element that can exist. Atoms consist of negatively-charged electrons orbiting a positive nucleus. Inside the nucleus are positively-charged proton/s and electrically neutral neutrons. Because protons have a charge of +1, and electron have a charge of -1, an atom has an equal number of protons and electrons, making it electrically neutral. Atoms can lose or gain electrons, however, to gain a full valence (outer shell) of electrons. When this happens

the structure of the atoms has always puzzled scientists, the idea of the atom had changed throughout the history of Earth. Democritus had originally issued the idea of atoms. (Doc 1) He proposed that the materials could be broken down until the thing couldn’t be broken down anymore. (OI) He named this little unit the atom, and this means “indivisible.” (OI) After that, research began to fully know what the atoms is and what it is made out of. After centuries of research, the atom we all know is founded

Atoms are made up of three tiny elements, a negative charge particles that spin around the shell outside of the nucleus, and it also consists of a protons that has a positive charge electron, and a neutrons that has neutral or no charge particles. Normally, protons and electrons balance each other by numbers to allow the atom acquire an electrically neutrally charge. The most easily shared electrons are the electrons furthest away from the nucleus of an atom. Ions are the atoms that are missing from

image of an atom has changed throughout history. The atom is the smallest unit to make all matter. Every solid, liquid and even gas has matter composed of atoms.  Many people have contributed to our understanding of atoms that dates back to as far as Ancient Greece. That goes to show how much work scientists have put in to help us unlock more doors to life.  The understanding of the structure of atoms has changed throughout history. The first documented case of the discovery of atoms dates back to
