Atomic nucleus

Today we'll learn :     1. Nuclear energy   2. The conservation of energy and mass   3. Thermonuclear energy   4. Power     1. Nuclear energy          In the previous post ( Work,energy and power part 2 ) we have discussed the energy changes which lead to the generation of electricity in a coal-burning electric power station. In a nuclear electricity generating installation the heat required for raising steam is provided by a nuclear reactor instead of coal furnance...Read Full Story

which in turn are made of protons, neutrons, and electrons, like so. All atoms have different numbers of protons, neutrons and electrons. protons, neutrons, and electrons make up all the planets, stars, gas, electrons, protons, and neutrons. The number and arrangement of these protons/electrons: 2. # neutrons: 2. Atomic mass: 4.002602 Figure 1 shows a schematic representation of atoms, electrons, protons, their protons, neutrons, electrons Organization of atoms 1) Nucleus - contains protons...Read Full Story

The human ostrich mind By and large the human mind takes the approach of an ostrich concerning the energy that it doesn’t perceive… If it can’t be perceived, then it’s not important. Electromagnetic energy was certainly important 500 years ago. After all, there was sunlight and heat, but people really didn’t frame their thoughts about it in energetic terms.   After all, at one time the sun was thought of as a God instead of energy. But in the last hundred years or so, we’ve built a lot of...Read Full Story

Here is a small presentation on atom. •Atoms are the building blocks ie basic units of matter. •They are the smallest unit of a chemical element having the properties of that element. •Atom is the smallest unit of matter that takes part in a chemical reaction. •Whole number of atoms of different elements combine together to give compound atoms(molecules). •They consist of three smaller particles called protons,neutrons and electrons. •Atoms are made of two divisions namely nucleus consisting...Read Full Story

We're learning about atoms. We built our own carbon atom on the wall with plastic balls and velcro. We wrote "nucleus" on the nucleus and used sticky note tabs for protons and neutrons. The other balls are the electrons orbiting the nucleus. We can remove the protons, neutrons and electrons and create atoms of helium or hydrogen, too.

This piece may appear to many readers (that is, I imagine it might if there were many readers) to be an exercise better suited for a medieval theologian, an effort which most people today would deem a waste of mental energy spent elaborating a dubious odd abstraction having no relationship to the real world. Nonetheless, I am going to report my observation of interesting parallels between the Christian doctrine of the Holy Trinity, as envisioned by the great medieval poet Dante Alighieri in...Read Full Story

By Dr. Jerimiah Crossderd To really grasp what a free radical is, you must look at at it from a chemical level of cells and molecules. Here's a quick chemistry lesson: The chemical composite of the human body is comprised of different types of cells. Cells are comprised of various types of molecules. Molecules consist of one or more atoms of one or more elements held together by a chemical bond. Atoms are made up of a nucleus, protons, electrons, and neutrons. The number positively charged...Read Full Story

INTRODUCTION Tidal energy is one of the oldest forms of energy used by humans. Indeed, tide mills, in use on the Spanish, French and British coasts, date back to 787 A.D.. Tide mills consisted of a storage pond, filled by the incoming (flood) tide through a sluice and emptied during the outgoing (ebb) tide through a water wheel. The tides turned waterwheels, producing mechanical power to mill grain. We even have one remaining in New York- which worked well into the 20th century. Tidal power...Read Full Story

By Dr. Lorna Mistranski The best way to fully comprehend what free radicals are is to look at them from a cellular level in that the human body is made up of all kinds of cells. The chemical bond of a cell is comprised of various types of molecules that are held together with one or more atom. Atoms are comprised of protons, neutrons, and electrons whereby the total amount of protons that are in the nucleus determine how many electrons will surround them. The role of the electrons is to...Read Full Story
