Rutherford created a planetary model for atoms after his experiments. Imagine if Rutherford's idea that electrons radiate energy

while orbiting around a nucleus was true. Which other model or scientific idea would have been strengthened by this? Bohr's model of the atom would have been strengthened because Bohr proposed that the energy of electrons is continuous. Bohr's model of the atom would have been strengthened because Bohr proposed that electrons can have only certain energy values. The idea that atoms are unstable would have been strengthened because the orbiting electron would lose energy and fall into the nucleus. The idea that atoms are unstable would be strengthened because the orbiting electron would absorb energy while moving and escape the pull from the nucleus.

Answer:

The idea that atoms are unstable would have been strengthened because the orbiting electron would lose energy and fall into the nucleus.

Explanation:

Based on classical mechanics an electron would spiral and fall on the nucleus thus collapsing the atom. But it was quantum mechanics that proposed that electrons move in definite orbits around the nucleus. Electrons absorb a definite quantum of energy and move from a lower state to an excited state. Also electrons release a definite quantum of energy and move from excited to more stable state.

An atom of 125Sn has a mass of 124.907785 amu. Calculate the binding energy in MeV per atom. Use the masses: mass of 1H atom = 1
Ksenya-84 [330]

Answer:

1.06×10³ MeV/atom

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

Also, atomic number of Sn = 5 0

Thus, the number of protons = 50

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Mass number = Number of protons + Number of neutrons

125 =  50 + Number of neutrons

Number of neutrons = 75

Mass of neutron = 1.008665 amu

Mass of proton = 1.007825 amu

Calculated mass = Number of protons*Mass of proton + Number of neutrons*Mass of neutron

Thus,  

Calculated mass = (50*1.007825 + 75*1.008665) amu = 126.041125 amu

Given mass = 124.907785 amu

<u>Mass defect = Δm = |126.041125 - 124.907785| amu = 1.13334 amu </u>

The conversion of amu to MeV is shown below as:-

1 amu = 931.5 MeV

<u>So, Energy = 1.13334*931.5 MeV/atom = 1.06×10³ MeV/atom</u>

Which of the following elements would require the most energy to
umka2103 [35]

Option D:  Chromium would require the most energy to convert one mole of gaseous atoms into gaseous ions each carrying two positive charges.

<h3>What does the term “ionization energy” mean? </h3>

The ionization energy measures an element’s ability for participating in any chemical processes that calls up for the creation of ions or the donation of other electrons.

It is defined as the energy that any electron present in a gaseous atom or ion has in order to absorb so that it comes out of the influence of the nucleus and hence freely move

Ionization energy is also said as the minimum energy required to remove the most loosely bound electron that is present in an isolated gaseous atom or a positive ion or a molecule.

It can be easily connected to the type of chemical bonds that exist between the components in the compounds that they form.

<h3>Which element ionizes most energetically?</h3>

Helium, because it has the highest first ionization energy, whereas francium has one of the lowest.

Which option is an example of a chemical property?
strojnjashka [21]
Answer: B= Rusting ability
Explanation:
Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.
Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.
1. Boiling point: is a physical property as there is a change of state.
2. Rusting ability: is a chemical property as there is formation of new substances.
3. Melting point: is a physical property as there is a change of state.
4. Density: is a physical property as there is no formation of new substances.
