Rutherford's Planetary model - ✔️✔️Which atomic model(s) would you be able to use as evidence
to support the claim "atoms are composed of mostly empty space?"
Yes because it can be tested through observations and experiments. - ✔️✔️"Does the planet Venus
have phases like the moon?" Is this question a scientific question?
increase because of the repulsive force between like charges. - ✔️✔️As two protons move toward
each other, the potential energy of the system will -
True because by definition a compound must have at least two types of elements. - ✔️✔️One part
of Dalton's Atomic Theory states:
Compounds are formed by combinations of atoms from two or more elements.
Is this statement currently considered to be true or false and why?
All atom contain electrons. - ✔️✔️Thomson discovered that the type of metal used for the cathode
did not affect the behavior of the cathode ray. What claim does this piece of evidence support?
During a collision energy will be transferred from the surrounding Xe atoms to the system of two Xe
atoms and the stable interaction will be overcome. - ✔️✔️Consider the container of Xe atoms
where two Xe atoms of interest are interacting (the system) and are surrounded by other Xe atoms
in the system. The surrounding Xe atoms have more energy than the system. Which direction would
you predict the energy would be transferred and what would happen?
The electrostatic force would become weaker. - ✔️✔️How would the strength of the electrostatic
force change if the distance between two charged objects increased?
They are both attractive interactions and they both release energy when they are formed. -
✔️✔️Which of the following statements are true for both LDFs and covalent bonds?
LDFs between the O2 molecules are overcome. - ✔️✔️When oxygen boils -
