Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors

Also‚ I will discuss how other disciplines can influence nursing science. This will help understand how theoretical thinking has evolved.

Creationism was widely accepted‚ as a religious and a scientific concept Darwin knew what a huge impact his knowledge would make on the world when he released it‚ so he withheld his theory for 25 years.

indestructible - All atoms of an element are identical - Atoms of different elements have different masses - When elements react‚ their atoms combine in simple‚ whole number ratios Some of the details off Dalton’s original theory are now known to be incorrect. But the core concepts of the theory (that chemical reactions can be explained by the union and separation of atoms‚ and that these atoms have characteristic properties) are foundations of modern physical science. 4.

multiple scientists that contributed to the creation of the first Atomic Theory: Democritus‚ Antoine Lavoisier‚ Joseph Proust‚ and John Dalton. Dalton took the information that he had taken from the three scientists prior to him and put everything into one theory. The Atomic Theory is the most well-known and accurate theory we know right now. Later on in history‚ more scientists came to contribute to the understanding of the Atomic Structure. These scientists included: Sir J.J. Thomson‚ Robert Millikan

Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third‚ all the atoms were different from all the other atoms. Fourth‚ atoms of different elements combined together in equal numbers to form compounds. Fifth and final

of our understanding of the structure of atom. New Zealand scientist Ernerst Rutherford was the first to show that the atom is the building block of all matter that consists of a positively charged nucleus surrounded by tiny negatively charged electrons. The extraordinary achievements of these scientists have been instrumental development of chemistry over the past century. Today‚ we take the existence of atoms for granted. We can explain many aspects of the structure of the atom and in fact‚ current

The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called
