Dalton in ( 1808, 1904, 1911, 1540 ) said that atoms of the same ( compounds, elements, systems, protons ) had identical properties and those of ( similar, the same, metallic, different ) elements are different. ( Dalton, Rutherford, Thomson, Bohr ) in 1904, designed an atomic model where ( electrons, neutrons, protons, nucleus ) were incrusted in a ( neutral, negative, circular, positive ) sphere. Rutherford in ( 1904, 1911, 1915, 1880 ) drew an atomic model were the nucleus had got almost all the ( charge, clouds, electrons, mass ) of the atom and all the ( positive, negative, neutral, espherical ) charge, and he added ( protons, electrons, neutrons, elements ) in an electron cloud where it was located the ( positive, neutral, whole, negative ) charge. In 1913 ( Rutherford, Bohr, Thomson, Dalton ) specified the ( orbits, roads, droplets, thickness ) in the electron cloud and he detailed how ( protons, things, electrons, neutrons ) moved in them.

Question 9 of 13

1

What is represented by every letter?

Drag an answer into the correct orange point.

Symbol of the element

Name of the element

Group of the element

Atomic representation

Mass number

electron cloud

Atomic Number

Explanation

Question 10 of 13

1

Choose the correct staments about atoms and numbers:

Select one or more of the following:

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.

Select from the dropdown lists to complete the text.

The periodic table contains ( 119, 117, 118 ) elements ordered by their ( atomic, mass, electronical ) number. The system is divided into:
- ( eight, seven, nine ) rows called ( periods, groups, families )
- ( eighty, seventeen, eighteen ) columns, called ( periods, groups, places ) or families. Elements which belong to the same group have got ( different, electrical, similar ) chemical properties.
We can distinguish four general types of elements:
- ( Metals, Non metals, Semimetals ): They are electricity and heat conducted. They are in ( liquid, gas, solid ) state except Mercury.
- Semimetals: Their behaviour is ( metallic, bright, important ) or ( non bright, special, non metallic ) depending on the conditions.
- ( Non-metals, Noble gases, Semimetals ): They are heat and electricity bad conducted. They are in solid, gas and liquid state.
- ( Especial gases, Noble gases, King gases ): They do not combine with other chemical elements.
