Chem Radiation Test

QuestionAnswer
what r the 2 types of radiation particle & electromagnetic radiation
what are the 2 types of radiation classified as?(2 answers) ionizing or nonionizing
is ion/non ionizing radiation more dangerous ionizing
what happens to atoms when expose to ionizing radiation lose an electron and become a positively charged cations
what is a source of electromagnetic radiaiton that ppl are exposed to everyday lights, computer screens
what is a source of nuclear radiation ppl are exposed to everyday radon, cosmin rays
what is the most stable #neutrons:#proton ratio for small atoms 1 neutron: 1 proton
what is the most stable #neutrons:#proton ratio for large atoms 1.5 neutrons: 1 proton
why does the ratio change as the size of the atom increases? a larger atom has more protons, more neutrons are needed to buffer the replusive forced created by the increase in positive charged protons
what is the graph called that determines if an atom is stable band of stability
how do radioisotopes become more stable over time they decay into new isotopes and release radiation and energy during the process
what are the 3 most common types of radioactivity alpha, beta, gamma
which type of radioactivity is the most ionizing alpha
why type of radioactivity is mose penetraing gamma
when does nuclear fission occur when a neutron collides w an atom and causes it to split apart into new atoms and more neutrons. they then collide w other atoms to create a chain reaction
when does fusion occur when smaller isotopes merge together to form a larger atom
what is fusion initiated by energy and pressue
does fission release or tkae in energy? release
does fusion release or tkae in energy? release
why type of nuclear process is used in todays nuclear power plants fission
what type of nuclear process is currently being researched as a possible fuel source in nuclear power plants of the future? fusion, more energy efficient and less radioactive waste
what challenged does the current research on fusion face? fusion conditions require a very high temp and pressure

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
