Periodic table. Quiz

Which statement about elements is correct?

• Most elements are metals

• Most elements are non-metals

• There are about the same number of metals and non-metals

• Most elements are neither non metals nor gases

Most metallic elements are located in the right side of the periodic table

• True

• False

One of these is a characteristic of non-metals

• They are shiny (Lustrous) but they do not conduct heat very well

• They are good conductors of electricity, but bad at conducting heat

• They are not good conductors of electricity, but can appear at the three states of matter

• They are good conductors of heat, also appearing at the three states of matter

Group II has the alkaline earth elements, who explode at contact with air

• True, because the alkaline composition they have makes them unstable, that´s why they are on the extreme of the table

• False, The alkaline earth elements are less violent than group I elements

• True, the lower the number of the group, the higher the violence of the explotion

• False, the alkaline earth elements are not unstable

The vertical rows of the periodic table are known as

• Periods

• Groups

• Aisles

• Neither of the options

The horizontal rows of the periodic table are known as

• Groups

• Periods

• Series

• Aisles

The transition elements are located

• on the right side of the periodic table

• on the left side of the periodic table

• in central section of the periodic table

• Under the central section of the periodic table

Elements that have properties of both metals and nonmetals:

• metalloids or semi metals

• inert gases

• transition metals

• Noble gases

An element's atomic number is always a reflection of...

• The number of protons it has in it´s highest level of energy

• The number of protons it has in total

• The number of protons it has before making a chemical reaction

In general, nonmetals...

• have low electrical and thermal conductivities

• have high chemical and heat conductivities

• have high electrical and thermal conductivities

• have high electrical and water conductivities
