Question 1
Question
When was the first idea of atom found?
Answer
-
In the 6th century BC
-
In the 5th century BC
-
In the 5th century
-
In Roman era
Question 2
Question
The nucleus of an atom is located at the centre.
Answer
- True
- False
Question 3
Question
Choose the correct answers about the electron cloud:
Answer
-
It is the internal part of the atom
-
It has got the negative charge of the atom
-
It has got protons spinnng in orbits
-
It is the external part of the atom
-
It has got electrons turning in orbits
Question 4
Question
All atoms have the same [blank_start]internal[blank_end] structure made up of: the [blank_start]nucleus[blank_end], very [blank_start]smalll[blank_end] compared to the size of the atom and the [blank_start]electron[blank_end] [blank_start]cloud[blank_end], the external area of the atom which is much larger than the [blank_start]nucleus[blank_end].
Answer
-
internal
-
nucleus
-
smalll
-
electron
-
cloud
-
nucleus
Question 5
Question
The Atomic Theory was admitted in 1904.
Answer
- True
- False
Question 6
Question
Dalton in [blank_start]1808[blank_end] said that atoms of the same [blank_start]elements[blank_end] had identical properties and those of [blank_start]different[blank_end] elements are different. [blank_start]Thomson[blank_end] in 1904, designed an atomic model where [blank_start]electrons[blank_end] were incrusted in a [blank_start]positive[blank_end] sphere. Rutherford in [blank_start]1911[blank_end] drew an atomic model were the nucleus had got almost all the [blank_start]mass[blank_end] of the atom and all the [blank_start]positive[blank_end] charge, and he added [blank_start]electrons[blank_end] in an electron cloud where it was located the [blank_start]negative[blank_end] charge. In 1913 [blank_start]Bohr[blank_end] specified the [blank_start]orbits[blank_end] in the electron cloud and he detailed how [blank_start]electrons[blank_end] moved in them.

Question 10
Question
Choose the correct staments about atoms and numbers:
Answer
-
The mass number is determined by the number of protons and electrons.
-
The atomic number is the number of protons.
-
The charge of an atom is calculated with protons and electrons.
-
The number of neutrons is the number of protons plus the number of electrons
-
The mass number is the addition of protons and neutrons
-
In the Periodic system of elements, they are ordered by their mass numbers
-
If an atom has got the same number of electrons and protons, this atom is neutral.

-
The mass number is twelve
-
The atomic number is twelve
-
It has got twelve electrons

Question 13
Question
The periodic table contains [blank_start]118[blank_end] elements ordered by their [blank_start]atomic[blank_end] number. The system is divided into:
- [blank_start]seven[blank_end] rows called [blank_start]periods[blank_end]
- [blank_start]eighteen[blank_end] columns, called [blank_start]groups[blank_end] or families. Elements which belong to the same group have got [blank_start]similar[blank_end] chemical properties.
We can distinguish four general types of elements:
- [blank_start]Metals[blank_end]: They are electricity and heat conducted. They are in [blank_start]solid[blank_end] state except Mercury.
- Semimetals: Their behaviour is [blank_start]metallic[blank_end] or [blank_start]non metallic[blank_end] depending on the conditions.
- [blank_start]Non-metals[blank_end]: They are heat and electricity bad conducted. They are in solid, gas and liquid state.
- [blank_start]Noble gases[blank_end]: They do not combine with other chemical elements.
