◉ How many electrons can you fit in the first, second and third
shells? Answer: Shell 1 : 2 electrons
Shell 2 : 8 electrons
Shell 3 : 8 electrons
◉ What is an Electronic structure? Answer: A set of number to show
the arrangement of electrons in their shells, eg. [2,6]
◉ C2 The periodic table Answer:
◉ What did John Newlands periodic table look like? Answer: He
arranged the elements in order of increasing atomic mass, he saw
that every eighth element reacted in a similar way
◉ What did Dmitri Mendeleev's periodic table look like? Answer: He
arranged the elements in order of increasing atomic mass, he
,switched the order of some elements to the fitted in the patterns of
other elements. He left gaps for undiscovered elements
◉ What does the modern periodic table look like? Answer: Elements
are arranged in order of atomic number, the elements are organised
in groups and periods which have the similar properties
◉ Why are elements in the periodic table grouped the way they are?
Answer: Elements with similar chemical properties are grouped
together in groups
◉ Why do elements in a group have similar chemical properties?
Answer: Elements in a group have similar chemical properties
because they all have the same number of electrons in their outer
energy level therefore react similarly
◉ What are the names of group 1, 2, 7 and 0? Answer: Group 1:
alkali metals
Group 2: alkaline earth metals
Group 7: halogens
Group 0: noble gases
◉ Where are the metals and non-metals located on the periodic
table? Answer:
,◉ What happens to metals when they react? Answer: When metals
react they lose electrons to achieve a full outer energy level
◉ What ions do metals from group 1 and 2 form? Answer: Group 1
form 1+ ions
Group 2 form 2+ ions
◉ Name the elements in Group 1 Answer: Lithium, Sodium,
Potassium,
Rubidium, Cesium, Francium
◉ Describe the reaction of a group 1 metal and oxygen in terms of
electrons Answer: In the reaction one group 1 metal transfers its
outer electron to the oxygen another group 1 metal does the same,
now all the atoms have a full outer energy level. The metals have a
1+ charge and the oxygen has a 2- charge
◉ Describe the reaction of a group 1 metal and chlorine in terms of
electrons Answer: In the reaction a group 1 metal transfers its outer
electron to the chlorine, now both atoms have a full outer energy
level. The metals have a 1+ charge and the chlorine has a 1- charge
◉ What is the word equation for the reaction of group 1 metals and
water? Answer: Metal + Water →
, Metal Hydroxide + Hydrogen
◉ Describe the reaction of the first three group 1 metals and water
Answer: When water reacts with lithium the reaction is fast and
there is fizzing. When it reacts with sodium the reaction is very fast
and gas is produced. When it reacts with potassium the reaction is
extremely fast and there is a small flame. In all the reactions the
water turns alkaline
◉ Describe the correlation of the reactivity of a group 1 metal and
it's location in the table Answer: Group 1 metals react faster as you
move down the column
◉ Why are group 1 metals more reactive as we move down the
group? Answer: As we move down the group the outer electron is
less attracted to the nucleus and easier to lose because it has a
greater distance between the positive nucleus
◉ Name some properties group 1 metals Answer: Group 1 metals
have low melting points and a low density, they are soft metals and
react very rapidly
◉ What elements are in group 7? Answer: Fluorine, Chlorine,
Bromine, Iodine, Astatine
