    Democritus (400 BC)

    補足(例文と訳など)

    答え

    • Greek, Made the original atomic theory. He belived atoms were always moving and came in different sizes. Atoms are indivisble (atomos)

    解説

  • 2

    James Chadwick (1932)

    補足(例文と訳など)

    答え

    • Discovered the neutrons in the atom.

    解説

  • 3

    quark

    補足(例文と訳など)

    答え

    • Smallest part of an atom. Building block that make protons and neutrons.

    解説

  • 4

    isotope

    補足(例文と訳など)

    答え

    • Different amount of protons and neutrons compared to the same stable atom.

    解説

  • 5

    Heisenberg and Schrodenger (1925)

    補足(例文と訳など)

    答え

    • Formed a model of a complete atom as interacting waves they made the electron cloud made the electron cloud model.

    解説

  • 6

    Dmitri Mendeleev (1869)

    補足(例文と訳など)

    答え

    • He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.

    解説

  • 7

    John Dalton (1803)

    補足(例文と訳など)

    答え

    • Developed modern atomic theory:, •All elements are made up of tiny indivisible particles, known as atoms., •Atoms of the same element are identical with respect to their size, weight, and properties., •Atoms of different elements are different from each other and can be identified by their relative weights, •Atoms of two or more different elements combine together to form chemical compounds

    解説

  • 8

    electron

    補足(例文と訳など)

    答え

    • Negatively charged particle of atoms. Much smaller then protons and neutrons. Found in clouds that surround the nucleous of an atom.

    解説

  • 9

    proton

    補足(例文と訳など)

    答え

    • Have a positive electrical charge; nearly the same size as neutrons, and are much larger then electrons, they are made up of 2 up quarks and 1 down quark. Located in nucleus.

    解説

  • 10

    neutron

    補足(例文と訳など)

    答え

    • No charge. Located in nucleus. Same size as proton. 2 down quarks and 1 up quark form this subatomic particle.

    解説

  • 11

    atomic number

    補足(例文と訳など)

    答え

    • Is the number of an element on the periodic table (number of protons)

    解説

  • 12

    nucleus

    補足(例文と訳など)

    答え

    • Made up of protons and neutrons (besides hydregon) and it is 99% of the mass of an atom. Is much smaller then an atom (100,000x).

    解説

  • 13

    ion

    補足(例文と訳など)

    答え

    • Is different number of protons then electrons.

    解説

  • 14

    atom

    補足(例文と訳など)

    答え

    • The smallest sized piece that elements come in. Small but heavy nucleus (protons and netruons) as its center and a cloud of tiny fast moving electrons orbit around the nucleus. Made up of mostly empty space.

    解説

  • 15

    Aristotle (300 BC)

    補足(例文と訳など)

    答え

    • Greek, and came up with a theory of atoms being different sizes he developed the four element (water, fire, earth, air) It was used for 2000 years until proven wrong.

    解説

  • 16

    atomic mass unit (amu)

    補足(例文と訳など)

    答え

    • Is the total mass of one atom of an element.

    解説

  • 17

    Niels Bohr (1913)

    補足(例文と訳など)

    答え

    • Model that depicts the atom as a small positively charged nucleous surrounded by electrons. He had them orbiting in specific places.

    解説

  • 18

    Ernest Rutherford (1911)

    補足(例文と訳など)

    答え

    • The father of nuclear physics. In 1911, he postulated that atoms have their positive charge (protons) concentrated in a very small nucleus.

    解説

  • 19

    Robert Bunsen (1855)

    補足(例文と訳など)

    答え

    • He investigated emission spectra of heated elements, and with Gustav Kirchhoff discovered caesium (in 1860) and rubidium (in 1861). The Bunsen-Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff

    解説

  • 20

    Joseph John "J. J." Thomson (1897)

    補足(例文と訳など)

    答え

    • He is credited for the discovery of the electron and of isotopes, and the invention of the mass spectrometer.

    解説

  • 21

    mass number

    補足(例文と訳など)

    答え

    • Tells how many protons and neutrons in an atom. (mass - protons = neutrons)
