CHEM 1

Lesson: 12 - 13 Isotopes. Molecules, Ions

QuestionAnswer
(BLANK) are atoms of the SAME ELEMENT that have the same number of PROTONS but DIFFERENT number of NEUTRONS Isotopes
(BLANK) of an element have the same atomic number but different mass number. isotopes
The (BLANK) of the element depends on the number of protons or electrons but not the neutrons identity
Hydrogen with 1 electron and 1 proton, no neutron mass number of 1 Protium
Hydrogen with 1 electron, 1 proton, and 1 neutron mass number of 2 Detrium
Hydrogen with 1 electron, 1 proton, and 2 neutron mass number of 3 Tritium
Proton + Neutron = ? Mass Number
Mass number - Protons = ? Neutrons
To identify a specific isotope of an element, write the name of the element followed by a hyphen and the mass number of the isotope. What does it look like if Oxygen with a mass number of 16? Oxygen - 16
Name which isotope this is a common use of: Used for hydrogenation; a process where molecular hydrogen is added to react with another compound to treat substances. Protium
Name which isotope this is a common use of: Used in prototype fusion reactors and has their application in military, industrial and scientific fields Deuterium
Name which isotope this is a common use of: Used as fuel in some nuclear fusion reactions Tritium
Name which isotope this is a common use of: It makes up for 18% of the human body. Sugar, glucose, proteins etc. are all made of it. Carbon - 12
Name which isotope this is a common use of: Has been used safely as a tracer in many studies over many years, for example, in the form of 13C-glucose, 13C-palmitate and 13C-leucine to investigate carbohydrate, fat and amino acid oxidation, respectively Carbon - 13
Name which isotope this is a common use of: Carbon Dating process Carbon - 14
Name which isotope this is a common use of: For respiration Oxygen - 16
Name which isotope this is a common use of: can be used as a tracer in the study of cerebral oxygen utilization Oxygen - 17
Name which isotope this is a common use of: for the production of Flourine - 18 Oxygen - 18
Name which isotope this is a common use of: Injected into limb to detect blood clot Oxygen - 18
Name which isotope this is a common use of: Detect and treat cancer/Use to kill bacteria Cobalt - 60
Name which isotope this is a common use of: Detect functions of Thyroid Gland Iodine - 131
Name which isotope this is a common use of: Added to fertilizer to study plant processes Phosphorous - 32
Name which isotope this is a common use of: Added to fertilizer to study plant processes Nitrogen - 15
Name which isotope this is a common use of: Use to kill bacteria Cesium - 137
Name which isotope this is a common use of: Use for diagnosis and treat of diseases Fluorine - 18 or Gallium - 67
Name which isotope this is a common use of: Use for diagnosis and treatment of diseases Gallium - 67 or Fluorine - 18
(BLANK) are made up of atoms that are chemically bonded together Molecules
(BLANK) are ELECTRICALLY NEUTRAL Molecules
(BLANK) can be DIATOMIC which means contain only of two atoms. ex. (homonuclear) Cl(s-subscript)2, N(s)2, (heteronuclear) HCI, CO Molecules
Molecules can be (BLANK) which means containing more than two atoms ex. O(s)3, H(s)2O, NH(s)3,CH(s)4 Polyatomic
(BLANK) are atoms or molecules that have a charge, meaning the number of protons is not equal to the number of electrons giving the atom either a positive or negative net charge ex. K(S)+, AL(S)+3, Ca(S)2+ CL(S)-, N(S)3-, CO(s)3(S)2-. H(s)O(S)+. etc. Ions (S - Superscript)
Positively charged ions that form from neutral atoms Cation
Negatively charged ions that form from neutral atoms Anion
(BLANK) make cations metals
(BLANK) mainly make anions Nonmetals
ATOMS are (BLANK) they have the same number of protons and electrons NEUTRAL
Atoms become ions when it loses or gains (BLANK) . electrons
TRUE OR FALSE: When an ion is formed, the number of protons changes. FALSE (When an ion is formed, the number of protons DOES NOT change.)
TRUE OR FALSE: Neutral atoms (metals) can be turned into positively charged ions by removing one or more electrons TRUE
ATOMS (nonmetals) that gain extra electrons become (BLANK) charged negatively
atomic mass - no. protons = ? neutrons

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:
