Question

CAN SOMEONE PLEASE CHECK MY ANSER PLASE

Protons and electrons naturally repel each other; therefore, protons stay in the nucleus.

True
False -----


Protons and electrons naturally attract each other, but the nucleus overcomes this electrostatic interaction by nuclear forces.

True------
False


The two forces most responsible for holding the atom together are:

gravitational and weak
electromagnetic and strong nuclear ------
strong nuclear and weak
gravitational and electromagnetic


Rutherford's model of the atom was similar to Bohr's model because they both thought that:
electrons were located in the nucleus of the atom
the nucleus of the atom was centrally located in the atom and was positively charged---
the nucleus was negatively charged and that the electrons were positively charged
electrons were too small in size to affect the properties of atoms

Bohr looked to improve upon Rutherford's model of the atom because Bohr thought that Rutherford's model:

was totally incorrect
needed to relocate the protons and neutrons
was not stable because the electrons did not have set orbits------
did not account for the positive charge of the protons

One of the important shortcomings of the Bohr model of the atom was that:
it did not distinguish between protons and electrons
it specified both definite location and momentum (energy) for an electron------
it showed that all electrons have equal energies
electron energies cannot be calculated


The scientist most often credited with the idea that a quantum of light (photon) can act as a particle is:

Schrödinger
de Broglie
Einstein------
Heisenberg


The Heisenberg Uncertainty principle states that:

the wave nature and the particle nature of matter are unrelated to one another
the wave nature and the particle nature of matter are complementary
the wave nature and the particle nature of matter are directly proportional to one another
the wave nature and the particle nature of matter are both able to be precisely calculated simultaneously-------

Electrons occupy certain high probability areas known as orbitals.

True------
False

the uncertainty principle states that the position and velocity cannot both be measured,exactly, at the same time (actually pairs of position, energy and time)
uncertainty principle derives from the measurement problem, the intimate connection between the wave and particle nature of quantum objects
the change in a velocity of a particle becomes more ill defined as the wave function is confined to a smaller region
the wave nature to particles means a particle is a wave packet, the composite of many waves
many waves = many momentums, observation makes one momentum out of many
exact knowledge of complementarity pairs (position, energy, time) is impossible
complementarity also means that different experiments yield different results (e.g. the two slit experiment)
therefore, a single reality can not be applied at the quantum level
the mathematical form of the uncertainty principle relates complementary to Planck's constant
knowledge is not unlimited, built-in indeterminacy exists, but only in the microscopic world, all collapses to determinism in the macroscopic world



True
