Basic Concepts of Atomic Theory: Investigating the Atom homework help at myhomeworkhelp.com
Physics studies all known types of matter and its associated concepts in order to develop an understanding of the workings of the universe. Students struggle to understand Physics due to its complex concepts and formulas. However, if you ensure that your key concepts are clear, everything else will slowly start falling into place.
At myhomeworkhelp.com, we have accurate solutions to all your Physics assignment problems. Our Investigating the Atom homework help will guide you through some basic concepts of Atomic Theory for your better understanding.
Basic Concepts:
What is a matter?
A matter includes everything around us. It exists in three basic states- solids, liquids and gases. It is a fundamental concept innatural sciences like Physics which seek to study the nature of matter.
What is Atomic Theory?
Atomic Theory is a scientific theory that investigates the nature of matter. It stipulates that all matter is made up of microscopic particles called atoms.
What is an Atom?
An atom is the smallest unit of matter. It is made up of three subatomic particles- protons, neutrons and electrons. Each proton bears a positive charge and each electron carries one negative charge. Atoms are structuredwith a nucleus comprised of positively charged protons, surrounded by negatively charged electrons which exist in shells surrounding the nucleus. This is what our Investigating the Atom assignment help focuses on.
Structure of an Atom:
“Atom” originated from the Greek word “atomos” meaning “uncuttable” from Democritus’ original concept of an indivisible atom. Our Investigating the Atom homework help explainshow subsequent experiments and advances in modern science proved the existence of three subatomic particles- electrons, neutrons and protons.
Electronsare negatively charged particles with negligible mass, bound to the positively charged nucleus. The nucleus encompasses positively charged protons and electrically neutral neutrons. Nucleons account for the major mass of the atom.
Each stable atom is balanced by an equal number of protons and electrons which result in an equal number of positive and negative electrical charges. An excess of electrons form a negatively charged ion and a surplus of protons forma positive ion. The atomic number of any element is equivalent to the number of protons present in its nucleus. This determines an element’s place in the periodic table.
History of Atomic Theory
This Investigating the Atom homework help gives you a detailed timeline of scientific theories that contributed to our modern concept of the atom:
- “Atomos” theory from Greek philosopher Democritus
- Dalton’s Billiard Ball model
- Thomson’s discovery of the electron and the Plum Pudding model
- Rutherford’s gold foil experiment, discovery of the proton and the Nuclear model
- Chadwick’s discovery of the neutron
- Bohr’s Planetary model
- Schrodinger’s Wave model and Electron Cloud
Our Investigating the Atom assignment help will elaborate upon each experiment and theory for your clarity whenever you need.
