Physical Science
To see if we got science questions down and if we understand it or not. But if you know you science than congrats if you don't continue studying.
- 1.When is an atom unlikely to react ?
- A.
An atom is unlikely to react because when the highest occupied energy level of an atom is filled w| electrons, the atom is stable.
- B.
An atom is unlikely to react when because when the highest occupied energy level of an atom is filled w| protons and the atom is unstable
- C.
An atom is unlikely to react because when the lowest occupied energy level of an atom is filled with protons, the atom is stable
- D.
An atom is unlikely to react because when the highest occupied energy level of an atom is filled with protons, the atom is unstable
- 2.What does an electron dot diagram shows and why is it helpful ?
- A.
An electron dot diagram is a is a model of the nucleus in which each dot represents a v.e [valence electron]. Its helpful because is shows how many protons are represented & how likely an atom is to react .
- B.
An electron dot diagram is a model of an atom in which each dot represents a proton . Its helpful because it shows how many v.e [ valence electron ] are present & how likely an atom is to react .
- C.
An electron dot diagram is a model of an atom in which each dot represents a v.e [ valence electron ] Its helpful because it shows how many v.e are present & how likely an atom is to react .
- D.
An electron dot diagram is a model of the nucleus in which each dot represents a proton . Its helpful because it shows how many protons are present & how likely an atom is to react .
- 3.What is one way in which atoms of elements can achieve stable electron configuration ?
- A.
One way in which atoms of elements can achieve unstable electron configuration is through the transfer of the v.e [ valence electron ] between the nucleus
- B.
One way in which atoms of elements can achieve stable protons configuration is through the transfer of v.e [ valence electron ] between the atom
- C.
One way in which of elements can achieve stable electrons configuration is through the transfer of protons between atom.
- D.
One way in which atoms of elements can achieve stable electrons configuration is through the transfer of v.e [ valence electron ] between atom .
- 4.Describe the process of ionic bounding ?
- A.
Ionic Bounding occurs when an atom gives its v.e to another atom which gains the electron .
- B.
Ionic bounding occurs when an element give its w.e to another element which gains the electron.
- C.
Ionic bounding occurs when an atom gives protons to another element which gains the electron
- D.
Ionic bounding occurs when an atom gives its v.e to another element in which gains an the proton
- 5.How does ionization energy affects the process ?
- A.
The amount of energy used to remove an electron is called ionization energy & electrons need to be removed in order to be transfered .
- B.
The amount of energy used to remove a proton is called ionization energy & protons need to be removed in order to be transfered .
- C.
The amount of energy used to remove a proton is called ionization energy & electrons needs to e removed in order to be transfered .
- D.
The amount of energy used to be remove a electron is called ionization energy & protons need to be removed in order to be transfered.
