Can Hydrogen make bond with alkali metals?
No, hydrogen is a nonmetal. It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.
Why only lithium chloride form hydride while other alkali metal does not do this?
no it is wrong. all of them are making.
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 happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.
Is potassium hydride a transition metal?
No- it is an alkali metal hydride.
Why lithium hydride is more stable than other alkali hydrides?
Lithium hydride is more stable than other alkali hydrides because it has a higher lattice energy due to its smaller size and higher charge density. This results in stronger ionic bonding within the compound, making it more stable. Additionally, lithium hydride's crystal structure is more tightly packed than other alkali hydrides, contributing to its stability.

When an acid is neutralised by an alkali the pH decreases.?
No, the pH increases.
WHAT IS sodium hydride?
Sodium Hydride is a strong base/alkali. It is an inorganic salt comprising of positively charged sodium ions, and negatively charged hydride (hydrogen) ions: Na+H-. It is a good source of the uncommon hydride ion. (NB Sodium hydride, NaH, is different to Sodium HYDROXIDE, NaOH, which is common table salt.)
What happens when you mix an acid with alkali?
When an acid is mixed with an alkali, a neutralization reaction occurs. This reaction results in the formation of water and a salt. The acidity of the acid decreases and the alkalinity of the alkali decreases as they react with each other.
What happens whey you add acid to alkali the pH solution gets?
it changes its colour into red.
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 happens to the pH when acid is added to an alkali does it go up or down?
When acid is added to an alkali, the pH decreases or goes down. This is because the acid donates hydrogen ions (H+) to the alkali, neutralizing the alkaline properties and shifting the pH towards neutrality or acidity.
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.
