Which trend decreases for metals down a group?
Melting Point
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
Why does electro negativity decrease while going down the periodic table?
Down the group the size of atom increases. Hence the force of attraction between the nucleus and the electrons of the next atom decreases. Or in other words, the electronegativity decreases down the group.
Which element in group two is most metallic?
The first. Going down metallicity decreases.
Why thermal stability decreases down the group?
Thermal stability decreases down the group due to the increase in atomic size and metallic character. Larger atoms have weaker metallic bonds, leading to decreased thermal stability as we move down the group. Additionally, the presence of higher energy levels and more electron shielding diminishes the attraction between the nucleus and outer electrons, making the elements less stable at higher temperatures.
How does the electro negativity change as you move down a group in the periodic table?
As we move down a group, electronegativity decreases.
Does the hardness of ice increase as the temperature decreases?
Yes, the hardness of ice increases as the temperature decreases.
Which trend decreases for metals down a group?
Melting Point
Why hydration energy decreases down the group in periodic table?
Hydration energy decreases down the group in the periodic table because the size of the ions increases as you move down a group. When ions are larger, they are less strongly attracted to water molecules. Therefore, larger ions exhibit lower hydration energies compared to smaller ions.
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
Electro chemical series down the group increases or decreases?
It increases
What increases down a group and decreases across a period?
Atomic radius
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 the nuclear charge change as you move down a group in the periodic table?
The nuclear charge decreases as you move down a group in the periodic table.
Why does electro negativity decrease while going down the periodic table?
Down the group the size of atom increases. Hence the force of attraction between the nucleus and the electrons of the next atom decreases. Or in other words, the electronegativity decreases down the group.
Why acidic character of oxides of group 15 elements decreases down the group?
The acidic character of oxides of group 15 elements decreases down the group because as we move down the group from nitrogen to bismuth, the ability of the oxide to donate protons decreases due to an increase in atomic size and metallic character, which results in a weaker acidity. Additionally, the anionic character of the oxide decreases as the metallicity of the element increases, leading to a less acidic nature of the oxides down the group.
Which element in group two is most metallic?
The first. Going down metallicity decreases.
