Atomic Structure Research Paper

The identity of each element is defined by the number of protons in its nucleus

Isotopes are different forms of the same element. They have the same number of protons and electrons, but are different in the number of neutrons. As an example, consider the three isotopes of Candium. M&Ms, Skittles, and Reese's Pieces. They are all types of Candium with only one proton in the nucleus and one electron in an energy level around the nucleus, but all three have different numbers of neutrons in their nuclei.

Radiation (also known as nuclear radiation) refers to particles or waves emitted by radioactive substance. Nuclear radiation comes from the waves from a nucleus. Ionising radiation can

The A simple definition of the word radioactiveis to have or develope a strong and dangerous form of energy. This could also be named radiation. A radioactive substance incvolves a very harmful form of energy that is developed betwen nuclear reactions. In the book "The Radioactive Boyscout" by ken Silversteint, there are several examples of radioactive substances being produced. The main character in the book is very as the title says "radioactive"

Explain how scientific observations led to the development of, and changes to, the periodic table.

Alpha, beta and gamma come from nuclear of an atom and they called radioactive, because it gives off radiation. These radiations absorb by different thickness of materials such as: Alpha radiation only travel few centimetre in the air, beta radiation travels tens centimetre in the air however gamma travel many meter in the air. If the substance is thicker, the more radiation it will absorbed.

Radiation was discovered in 1895 by Wilhelm Roentgen during a scientific experiment. Roentgen, classified radioactivity into three concepts: negative, positive, and electrically neutral. Radiation- is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Technology is created with radiation and humans are exposed to the aspect daily with tons or material; especially in the doctor’s office and everywhere else.

(OI) According to the chart, protons have a positive charge, neutrons have no charge, and electrons have a negative charge. (Doc 3) Each atom have a nucleus, where the protons and neutrons

2. An isotope is like a different version of an original atom. It has the same number of protons but the neutrons change. As a result, the atomic number remains the same but the mass number changes.

Protons, neutrons and electrons are different from one another; they have their properties and/or characteristics.

Thus, the above symbols denote, respectively, the mass-235 and mass-238 isotopes of uranium (symbol U), and the mass-1,-2,and -3 isotopes of hydrogen (symbol H). The mass-2 isotope of hydrogen is also called deuterium and the mass-3 isotope is also called tritium.

Multiple forms of the same element that have the same amount of protons but different number of neutrons in their nuclei.

I partially agree because in an atom, the number of electrons matches the number of protons. In spite of this, one element is distinct from another element if the number of protons are different.

The periodic table is a table that categorises and displays all of the chemical elements. It is made up of groups, periods and blocks. A group (also referred to as a family) are the columns of elements, there are 8 groups. The elements in each family have similar but not identical properties and they all have the same number of outer electrons. E.g. lithium (Li), sodium (Na), potassium (K) are all soft, white, shiny metals because they are all members of group 1. A period is each horizontal row of elements, there are 7 periods. In a period, the elements are not alike in properties, the first element in a period is always an extremely active solid, and the last element in a period is always an inactive gas. Properties change greatly across a given row. Each new period represents the next shell which electrons fill. A block is a region of the periodic, there are 4 blocks: S, D, P and F.

Also Beta Particles are radiation. Beta Particles are positive or negative electrons. They are like Alpha Particles, they are only dangerous if inhaled or ingested. Clothing or aluminum can stop Beta Particles. All of these types of radiation can be considered nuclear waste, but also often have uses. X Rays use radiation to examine us. Radiation is used in medicine, dentistry, and industries. Remember the next time you get an X- Ray you are exposed to radiation.
