1When was the first idea of atom found?
- AIn the 6th century BC
- BIn the 5th century BC
- CIn the 5th century
- DIn Roman era
2The nucleus of an atom is located at the centre.
- AVerdadero
- BFalso
3Choose the correct answers about the electron cloud:
- AIt is the internal part of the atom
- BIt has got the negative charge of the atom
- CIt has got protons spinnng in orbits
- DIt is the external part of the atom
- EIt has got electrons turning in orbits
4All 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].
- Ainternal
- Bnucleus
- Csmalll
- Delectron
- Ecloud
- Fnucleus
5The Atomic Theory was admitted in 1904.
- AVerdadero
- BFalso
6Dalton 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.

10Choose the correct staments about atoms and numbers:
- AThe mass number is determined by the number of protons and electrons.
- BThe atomic number is the number of protons.
- CThe charge of an atom is calculated with protons and electrons.
- DThe number of neutrons is the number of protons plus the number of electrons

13The 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.- A119
