carbon family https://www.britannica.com/science/tin. Tin consists of 50 Protons‚ 69 Neutrons and 50 electrons. (my citation for where i got this information is the periodic table you gave to us.) The atomic number of tin is 50 because the atomic number is usually the same number of protons. The atomic mass is 118.71 u. I used my knowledge from the recent years in biology and physical science to use the protons and neutrons to determine the atomic mass. Tin is a metal because it is ductile and it is

Structure of the Atom Dense nucleus composed of neutrons (0 charge) and protons (+ charge) and surrounded by orbital electrons (- charge). Neutrons and protons firmly held in the nucleus while electrons are very loosely held and are easy to remove. When electrons are removed from the atom‚ two charged particles (ions) are produced the positively charged atom and the negative electron. Energy is absorbed to remove the electron from the atom. Atomic Notation Chemical symbols such as C for

nucleus. * 1926: Erwin Schrodinger stated his development of the mathematical description that described the ways that electrons would follow in their orbits around the nucleus. * 1932: James Chadwick discovered the neutron that is no charge (neutral). He also found the neutron weighted slightly heavier than the proton. * 1939: Lisa Meitner published the first paper about nuclear fission. She predicted the existence of chain reaction‚ which contributed to the development of the atomic bomb

the atom‚ there is a nucleus. Within the nucleus‚ there are protons (+) and neutrons (neutral). To find the number of neutrons in an atom‚ you subtract the atomic mass from the atomic number. Atoms of an element can have different amount of neutrons. These are called Isotopes. 19.3 Unstable Nuclei and Radiation Positively charged protons in nuclei tend to repel one another. In order to make the nuclei stable‚ neutrons are present to dilute the forces of repulsion. It acts like a form of “Nuclear

number of neutrons is plotted versus the number of protons. Because the plot shows only the stable isotopes‚ this graph is often called the Nuclear Belt of Stability. The plot indicates that lighter nuclides (isotopes) are most stable when the neutron/proton ratio is 1/1. This is the case with any nucleus that has up to 20 protons. As the atomic number increases beyond 20‚ a different trend becomes apparent. In this range‚ it appears that a stable nucleus is able to accommodate more neutrons. Stable

Calculate the average mass of a sphere in this sample. (4.00 + 4.00 + 4.00 + 4.00)/4= 16.00/4= 4.00g Part 2: Now consider a sample that consists of four spheres‚ each with a different mass: blue mass is 4.00 g‚ red mass is 3.75 g‚ green mass is 3.00 g‚ and yellow mass is 1.25 g. * a. Calculate the average mass of a sphere in this sample

In case of Fission‚ the radioactive substance is placed on a plane surface‚ and enclosed in heavy machinery. Then the atomic particle neutron is projected to collide at a very high speed (70-80 times more than the regular speed). When the Neutron hits the atomic nuclei of radioactive substance‚ the energy of Neutron is act as breaking energy (ionisation energy)‚ which results in splitting of one atomic nuclei into two parts and gigantic amount of energy is released during

You nourish those cells with chemicals that are obtained from food. Life is all about chemicals and how they interact Concept 4.1 Life requires about 25 chemical elements Elements Humans and other organisms are examples of matter.

They tell us how the structure of the atom looks and how the number of protons‚ electrons‚ and neutrons affect how much energy that element can produce. If there are more electrons the element does not conduct any energy and if there are more

non-radioactive isotope of helium with two protons and one neutron. Also it sometimes called ‘tralphium’. According to many experts‚ helium-3 can be a clean nuclear power. There are many benefits of helium-3 but the most important problem is that there is very little helium-3 available on the Earth. First of all‚ I will give general some information about helium-3 isotope. Helium-3 | General | Name‚ symbol | Helium-3‚ 3He‚ He-3‚3He | Neutrons | 1 | Protons | 2 | Helium-3 is sought for
