8.1 STRUCTURE OF PERIODIC TABLE
Fill in the blanks
The vertical columns are called_. The horizontal rows are called_.
groups, periods
Name all orbitals and how many electrons each can hold.
s - 2e; p - 6e; d - 10e; f - 14e
Name two elements: one with the strongest metallic properties and one with the strongest nonmetallic properties.
Francium, Fluorine
What are metalloids?
Some elements that have properties of metals and nonmetals more at the same time.

Guess the element
The most abundant metal in the Earth’s crust. It is light and used in airplane construction, food packaging, car industry.
Aluminium
Which groups in the periodic table contain the most active metals and the least active nonmetals?
alkali metals and halogens
What does Pauling’s scale show?
electronegativity
True or false? At room temperature, all metals have a silvery lustre and are in the solid state.
False, Hg is in the liquid state

What should we look at in the periodic table to find out how many electrons are in the outermost electron shell of element?
group
Define the element with electron configuration: 1s²2s²2p⁶3s² 3p⁶4s²3d⁶
Fe
What is electronegativity?
Electronegativity is a measure of an atom's ability to attract shared electrons to itself.
Explain conductivity of heat and electricity of metals, nonmetals and metalloids.
metals - good conductor; nonmetals - poor conductor (except graphite); metalloids - semiconductor
My favourite colours
green and yellow
What can we say about an element’s electron configuration if we know its period in the periodic table?
number of shells
Write the electron configuration of aluminum.
1s²2s²2p⁶3s² 3p¹
Why is the electronegativity value of most noble gases zero?
Noble gases have a full outer shell of electrons, so they don’t attract electrons to form bonds.
Fill in the blanks
Metals have a tendency to _ electrons. Nonmetals have a tendency to _ electrons.
donate, receive
How many siblings do i have?
3 older brothers
Fill in the blanks
There are _ periods in the modern periodic table and each period begins with _ and ends with a _.
seven, alkali metal, noble gas
Explain the octet rule.
The octet rule states that atoms are at their most stable when they have the electron configuration of a noble gas.
Sort the elements in order of decreasing atomic radius: Ca,Mg, Sr, Be, Ba
Ba > Sr > Ca > Mg > Be
Complete the reaction:
aluminium (Al) + sulphuric acid (H₂SO₄) -> ?
aluminium sulphate (Al₂(SO₄)₃) + hydrogen (H₂)
