What is the group trend for the ionization energy for the alkali metals?
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
What trend does electroelectricity follow going down the periodic table?
Electronegativity DECREASES going down a group.
Why thermal stability of alkali metal hydride decreases down the group?
As the size of alkali metals increases down the group the M-H bond becomes weaker hence its stability decreases from LiH to CsH
How does metals or nonmetals change as you go down group 0?
As you go down Group 0 (also known as the noble gases), both metals and nonmetals tend to become less reactive. The noble gases are already very stable and unreactive, and this reactivity decreases even further as you move down the group. Metals in Group 0, called alkali metals, also become more reactive as you go down the group, while nonmetals in Group 0, known as halogens, become less reactive.
What is the Trend in first ionization energy across a period?
As one proceeds down the group 7A elements, the first ionization energy decreases. this means that the outermost electron is more readily removed as we go down a group.
What is the group trend for the ionization energy for the alkali metals?

Which trend decreases for metals down a group atomic radiusreactivity or melting point?
Melting points generally decrease as you go down a group for group I and group II metals. This does not apply to the transition metals. Reactivity of metals increases down a group due to a larger size and less effective charge between the nucleus and valence electrons. Atomic radius increases due to a higher principle number of electrons.
How does reactivity work with the elements going down the groups for metals and non metals?
Reactivity increases down the group for metals. It decreases down the group for non-metals.
What trend does the first ionization energy follow in the periodic?
It decreases when going down a group.
How does reactivity work with the elements when you go down the groups?
Down the group, reactivity decreases for non metals. It increases for metals.
What trend does the first ionization energy follow in the periodic table?
It decreases when going down a group.
What trend the first ionization energy follow in the periodic table?
It decreases when going down a group.
What is the periodic trend for elctronegativity?
Going down a group...electronegativity decreases Going across...electronegativity increases
What is the trend for ionic radius for medals?
if you mean metals ..... for the same valence the radius decreases across a period and increases down a family
Why the solubility of alkaline earth metals decrease down the group?
because down the group the cation becomes gets larger so the hydration energy decreases. so the solubility decreases
What trend does electro negativity follow going down the periodic table?
Electronegativity decreases down the group. Metallic character increases.
What trend does electroelectricity follow going down the periodic table?
Electronegativity DECREASES going down a group.
