Physical Characteristics of group 1 elements are(choose all that apply)
soft metals
low density
loat on the surface of water
grey shiny surface at room temperature.
Write the equation for the reaction of sodium with water.
The reactivity of alkali metals in
Group 1 is due to the tendency of
atom to donate its valence electrons.
atom to receive its valence electrons.
Why do the melting point
and boiling point of elements decrease when going down the group?
Group 1 elements are soft metals, with low density and float on the surface of water
Group 1 elements have one electron in the valence shell. In a chemical reaction, these atoms donate
one electron and form an ion with the +1 charge.
The increase in the atomic size
down the group will weaken the attraction force between the atoms. Therefore, less heat energy is
required to overcome the attraction forces between the metal atoms.
When alkali metals burn in oxygen gas,
black solid is produced
a white solid that is metal oxide will be formed
gas is produced
Reaction of chlorine with water will
produce
hypochlorous acid
hydrochloric acid
sulphuric acid
Why does the reactivity
of elements decreases when going
down Group 17?
Increasing
atomic size will cause the
valence shell to be further from
the nucleus. This will cause the
nuclear attraction force towards
the electrons to become weaker.
Thus, the difficulty in attracting
electrons to fill the valence shell
will increase.
Decreasing
atomic size will cause the
valence shell to be further from
the nucleus. This will cause the
nuclear attraction force towards
the electrons to become weaker.
Thus, the difficulty in attracting
electrons to fill the valence shell
will increase.
