History I used the oil drop experiment to determine the charge/mass of an electron. Back The Answer is Millikan.

History I gave us the Law of the Conservation of Mass. Back The Answer is Lavoisier.

Atoms and the Periodic Table This element has an atomic mass of 1.01? Back The Answer is Hydrogen

Atoms and the Periodic Table This element has 12 protons in its nucleus? Back The Answer is Magnesium.

Double Jeopardy

Atoms and the Periodic Table Write the nuclear symbol of the element with 24 protons and 28 neutrons. Back Cr The Answer is

Atoms and the Periodic Table What is the mass of an element with 25 protons, 25 electrons, and 30 neutrons? Back The Answer is 55.

Atoms and the Periodic Table Back The Answer is 34, 34, 46 IsotopeNumber of Protons Number of Electrons Number of Neutrons Selenium - 80 Complete the chart:

Atomic Parts I am the center of an atom. Back The Answer is the nucleus.

Atomic Parts When I change, the element changes? Back The Answer is the proton.

Atomic Parts When I am lost, an ion is created. Back The Answer is the electron.

Atomic Parts I change the atomic mass, but not the atomic number. Back The Answer is the neutron.

Random Points 200

Atomic Parts What subatomic particles have a mass that impacts the mass of the atom? Back The Answer is protons and neutrons.

Isotopes What do isotopes of the same element differ in? Back The Answer is neutrons.

Double Jeopardy

Isotopes Calculate the average atomic mass for carbon if its abundance in nature is 79.3% carbon-12, 13.3% carbon-13, and 7.4% carbon-14. Back The Answer is 12.3 g/mol

Isotopes One isotope of aluminum is aluminum-27. The 27 refers to the ______________ (two words). Back The Answer is mass number.

Isotopes The ____________________ of an isotope is the time required for half the nuclei in a sample of the isotope to undergo radioactive decay. Back The Answer is half-life

Double Jeopardy

Isotopes What is the half-life of an isotope if 150 g of a 600 g sample of the isotope remains after 2.0 years? Back The Answer is 1.0 years.

Laws The law that states that mass cannot be created or destroyed in ordinary chemical and physical changes. Back The Answer is Law of Conservation of Mass

Laws The law that states that a chemical compound always contains the same elements in exactly the same proportions by weight or mass. Back The Answer is Law of Definite Proportions

Laws During a chemical reaction, a group combines 5.00 grams of sodium and 7.72 grams of chlorine. The result of the reaction was grams of sodium chloride. Which law does this support? Back The Answer is Law of Conservation of Mass

Laws The law that states that when two elements combine to form two or more compounds, the mass of one element that combines with a given mass of the other is in ratio of small whole number. Back The Answer is Law of Multiple Proportions
