He claimed that matter was made of small, hard particles that he called “atomos.”
Democritis
Dalton
Moseley
Einstein
The scientist responsible for discovering the nucleus is:
Bohr
Rutherford
Schroedinger
Einstein
John Dalton stated:
Atoms are tiny, invisible particles.
Atoms of one element are all the same.
Atoms of different elements are different.
Compounds form by combining atoms.
All of the statements listed.
The currently accepted model of the atom is
the billiard ball model
the chocolate chip cookie model
the solar system model
the electron cloud model
Democritus stated that
electrons orbit the nucleus in fixed patterns
atoms are indivisible pieces of matter
atoms form substances in fixed ratios
at the center of the atom is a dense, positively charged nucleus
Dalton stated that
electrons orbit the nucleus in fixed patterns
atoms are indivisible pieces of matter
atoms form substances in fixed ratios
at the center of the atom is a dense, positively charged nucleus
Bohr's new contribution to atomic theory stated that
electrons orbit the nucleus in fixed patterns
atoms are indivisible pieces of matter
atoms form substances in fixed ratios
at the center of the atom is a dense, positively charged nucleus
Rutherford stated that
electrons orbit the nucleus in fixed patterns
atoms are indivisible pieces of matter
atoms form substances in fixed ratios
at the center of the atom is a dense, positively charged nucleus
The Electron Cloud Model is unique because
it places electrons in zones of probability
it treats electrons as both particles and waves
it is the currently accepted model of the atom
