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
How do the reactivity of the alkali metals change in group 1?
The reactivity of alkali metals increases as you move down Group 1 from lithium to francium. This trend is due to the decreasing ionization energy, which makes it easier for the alkali metals to lose their outermost electron and become more reactive.
Melting points of alkali metals?
The melting points of alkali metals decrease down the group on the periodic table. Lithium has the highest melting point at 180.5°C, while cesium has the lowest at 28.5°C. This trend is due to the decreasing strength of metallic bonds as the atomic size increases down the group.
Which trend decreases for metals down a group?
Melting Point
What is the trend for first ionization energy for the alkali metals?
The trend for the first ionization energy of alkali metals decreases as you move down the group from the top. This is due to the increase in atomic size and shielding effect, which allows easier removal of the outermost electron.

What are properties of alkali metals?
highly reactive, tarnish easily, low melting points, soft, low density, some have weak radiation also it is very flammable in water
Identify the trend in melting point from lithium to caesium?
The trend in melting point from lithium to caesium is that it increases. Lithium has the lowest melting point of the alkali metals, while caesium has the highest melting point. This trend is due to the increasing strength of metallic bonding as atomic size increases down the group.
What is the hardness of berkelium?
The hardness of berkelium, a synthetic element, has not been specifically measured. However, as a general trend for actinide elements, berkelium is expected to be relatively soft, like most metals in the actinide series.
Which elements are in the same group?
A group in the Periodic Table fits into a vertical column, so the first column is group 1, the alkali metals, lithium, sodium, potassium etc. They are grouped according to their abilities to combine with other elements, in other words there will be a common theme to their behaviour. So all the metals in group 1 will react with water in the same way, but you will see a trend as the behaviour shifts in nature down the group. In group 1 the reactivity increases down the group, so the metals fizz more vigorously when dropped into water.
What is the trend for first ionization energy for the alkali metals?
The trend for the first ionization energy of alkali metals decreases as you move down the group from the top. This is due to the increase in atomic size and shielding effect, which allows easier removal of the outermost electron.
What order of reactivity NOT activity are the metals Barium Lithium Radium and Sodium in?
The order of reactivity in these metals from least reactive to most reactive is: Barium, Radium, Sodium, Lithium. This is based on their tendency to lose electrons and form positive ions in chemical reactions. Barium and Radium are less reactive compared to Sodium and Lithium due to having a larger atomic size and higher electron shielding, making it harder for them to lose electrons.
What is the trend in melting point and boiling points of the elemets in group 1 and 7?
In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
What is the trend on production of carbon dioxide when metal carbonates react with HCl?
The carbonates of the metals in group I reacts easily.
