The periodic table we can find that correct statements are:
b) It is nonmetal that does not conduct electricity well
d) It is very unreactive
The periodic table is a method developed to group chemical elements based on their atomic number allowing to visualize many similarities between different chemical elements.
The peridot table is divided:
- Rows called periods, each begins with an element with a single electron in its last shell and ends in an element with eight electrons in its last shell
- Columns called a group, each element of the column has the same number of electrons in the last shell.
The properties of the elements in a column (group) are similar, for example group 8 (VIIIA) called noble gases has 8 electrons in its last shell, which is why it is full, which implies that they are non-reactive and because the electrons are not full. they can move before electrical fields therefore their electrical conductivity in small.
Let's analyze the different affirmations in scares that Argon is an element of group 8, it is a noble gas
a) False. The last layer is full, so it is non-reactive
b) True. As the last cap is full and the inner layers too, the electrons cannot move, so the electrical conductivity is very low.
c) False. It is a non-metal and does not conduct electricity
d) True. As the last layer is full, the reactivity is very small.
Conclusion with the use of the periodic table we can find the correct statements are:
b) It is nonmetal that does not conduct electricity well
d) It is very unreactive
