Quizizz Practice Quiz #2: Questions and Answers and important topics to learn and consider more about

Question Missed #1:

  • The three types of nuclear radiation in increasing order of penetrating power are (1) alpha rays, (2) beta rays, and (3) gamma rays

  • A helium nucleus with two protons and two neutrons is called an alpha (a) rays! - -Which consists of positively charged particles ( called a particles, where are deflected by the positively charged plates.

  • 83 protons in the nucleus of an atom make the atom naturally radioactive and is too many protons.

  • Fission is a type of activity that occurs in nuclear facilities

  • Fission is the action of ONE neutron hitting a nuclei and causing it to split into two smaller, and lighter nuclei!

  • -1^0e is an example of the gamma symbol

  • gamma elements are represented with negative numbers?

  • on a graph, the element(s) that are NOT Radioactive are the ones in the red wave? and are stable I think

    • on the same graph, the element(s) that are in a Unstable Region on the graph are the parts that are not included in the red wave!

  • The correct equation of U-238 alpha decay will be a u element with 92 protons and mass of 238 minus the Th element with 90 protons, and a mass of 234 to get the a element of 2 protons, and a mass of 4. * of course written with an arrow going to the Th element and then + the a element!

  • Beta particles (B) is a negatively charged particle emitted from a nucleus at a high speed!

    • Beta particles are small, fast-moving particles that have a fast moving electrical charge and are emitted from an atoms nucleus during radioactive decay

  • to balance an equation, make sure that the protons and the mass number line up by the protons being clear that they were subtracted, and the mass are subtracted as well.

  • Fusion is a reaction that also happens in the sun and the stars

  • Determining the half life of a graph:

    • determine the original amount of the substance

    • determine the amount of time for which the substance was measured

    • determine the remaining amount of the substance after the time

    • substitute these values into the half-life equation and solve for half-life!

  • original amount: 9.5

  • time passed since the substance was measured: 19.5

  • amount of substance remaining after that time: 4.5

  • fill in the half life equation: 4.5= 9.5(1\2)^19.5\^(19.5)1\2

  • One example of another nuclear radiation being emitted is beta

  • no more than 2 electrons can fit into ONE of the shapes ! (“How many electrons can fit into ONE s shape”?

  • An alpha particle has the symbol of He and 2 protons, and a mass of 4

  • A beta particle has the symbol of e and -1 protons, and a mass of 0

  • the gamma particle is energy

  • nuclear fusion is the nuclear reaction in the hydrogen bomb.

  • fusion is when an unstable nucleus undergoes decay and released energy and some type of particle from inside

  • on the graph, the element(s) that are in the red wave are in a Stable Region!

  • the numbers on the periodic table tell you the amount of protons, mass, and electrons in each element

  • a radioactive element is not stable but it is an example that some atoms have an unstable combination blend of protons and neutrons which is what is considered radioactive!

  • the purpose of an electron configuration is to identify the location of the electrons in different elemental atoms.

  • Alpha particles are a type of radiation that can be stopped by a sheet of paper or clothing

  • isotopes are heavier and or lighter versions of the SAME elemental atom due to a different number of NEUTRONS in the nucleus.

  • Yes! Radioactive Isotopes are used to treat Cancer and to help in medical Imaging.

  • The atomic bomb is an example of a fission nuclear reaction!

  • the split of smaller nuclei from one big nuclei is an example of nuclear fission

  • 6 and 8 isotopes of Lithium are radioactive!

  • The Lithium isotope 7 is stable

  • the beta radioactive electron is ejected from outside the nucleus of the atom where the electrons live in orbital because the high speed electron from a Beta decay comes from inside the nucleus or from the electrons that are on the outside of the nucleus in orbital

  • not all radioactivity is dangerous to humans and we receive small doses of radioactivity every day naturally, and without harm!

  • fission is the splitting of a big large nucleus into smaller, light nuclei and also occurs in Power Plants

  • The colors, and s, p, d, and f letters on he periodic table tells us the ring #, the radius, and the energy level of the electrons and where the element is located!

  • the strong nuclear force is known as the force that holds the protons and the neutrons together inside the nucleus because not all combinations of protons and neutrons create a stable nuclei!

    • and the strong nuclear force is need to hold together all of the postively charged protons together which allows them to not repel each other and fly away

    • this force also attracts the protons and the neutrons together to oppose the positive charge that repel one another

    • the neutrons presence adds a net attractive force to the inside of a nucleus and the adjacent neutron and proton and then two adjacent neutrons have only the strong nuclear force acting on them together! Because of this, is it a fair analogy to consider the neutrons to be the “glue” that holds together the nucleus

    • nuclei are unstable is they contain too few neutrons and if they contain more than 83 neutrons

  • * anything below 83 is stable

  • * C and B are not radioactive

  • * only C is stable?

  • it also

Next try:

  • A hydrogen bomb is a fusion nuclear reaction because the fuel ( lithium deuteride ) releases tritium and creates a spark from the heat and pressure that comes from the explosion

Topics to focus on:

  • gamma elements are represented with negative numbers?

  • on a graph, the element(s) that are NOT Radioactive are the ones in the red wave? and are stable I think

  • What is radioactive decay?

  • the half-life equation:

  • nucleus orbital

  • Beta decay comes from inside the nucleus or from the electrons that are on the outside of the nucleus in orbital
