Answer 1

5. Answer;

-Nucleus

-The results of Rutherford’s gold foil experiment demonstrated that the nucleus occupies a very small amount of the total space inside an atom

Explanation;

-In Rutherford's gold foil experiment, alpha particles that bounce straight back from the foil have struck nucleus in the gold atoms. Some of the alpha particles aimed at gold atoms bounced back, suggesting that a solid mass was at the center of the atom.

From this experiment, he concluded that; Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. Additionally, very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.

6. Answer;

-Atomic number

If element Q has 11 protons, its atomic number is 11.

Explanation;

-The atomic number or proton number of a chemical element is the number of protons found in the nucleus of an atom. It is identical to the charge number of the nucleus and also uniquely identifies a chemical element.

-In a neutral or uncharged atom, the atomic number is also equal to the number of electrons.

7. Answer;

-Energy shell or energy levels

The region in which an electron is most likely to be found is called a(an) energy shell or energy level.

Explanation;

An atom is the smallest particle of an element that can take part in a chemical reaction.

An atom contains of a small nucleus and the energy shells or energy levels. The nucleus of an atom contains protons and the nucleus while the energy levels contains electrons. Protons are positively charged which makes the nucleus to have a positive charge, while the electrons are negatively charged.

-In a neutral or uncharged atom the number of protons in the nucleus is equal to the number of electrons in the energy levels.

8. Answer;

Excited state

An atom in which an electron has moved to a higher energy level is in a(an) excited state

Explanation;

-Excited state of an atom is the sate at which electrons move to a higher energy than the ground state.

-When a valence electron absorbs energy, it enters what is known as an excited state. The excited state can commonly take the form of the electron jumping from its original energy level or orbital, also known as the ground state, to an empty orbital of a higher energy shell that is further away from the nucleus.

Answer 2

5.

The results of Rutherford’s gold foil experiment demonstrated that the nucleus occupies a very small amount of the total space inside an atom.

Further Explanation:  

• In Rutherford's gold foil experiment, the beam of alpha particles hit the thin gold foil. Some of them follow the same path after hitting the gold foil while some of them deflect from the path and bounces back indicating the presence of solid mass at the center of atom.  

• From this experiment, he concluded that most of the part in atom is empty because most α-particles go through the gold foil without being deflect. In addition, very few particles deflected from the path, indicating that very less space occupied by positive charge.

6.

If element Q has 11 protons, its atomic number is 11.

Further Explanation:  

• Atomic number of an element is number of protons present in nucleus of an atom. Atomic and charge number is same of the nucleus and identifies an element uniquely.

• In an atom, electron and proton are equal in number.

7.

The region in which an electron is most likely to found called an energy shell or energy level.

Further Explanation:  

• An atom consists of a small nucleus and energy shells or energy levels.

• Nucleus consist protons and nucleons while the energy level consist electrons.

• Charge on proton is positive while charge on electron is negative.

• In an atom, proton and electron are equal in number.

8.

An atom in which an electron has moved to a higher energy level is in excited state.

Further Explanation:  

• Excited state of the atom is a state, which occurs due to moving of electrons from a lower energy shell to higher energy shell.  

• When a valence electron absorbs energy from photons, it gets excited to a higher energy shell from a lower energy shell and occurs only when electron is already excited to its lower energy shell from a ground state.
