Answer:

Option D: it's ability to lose electrons

Explanation:

Alkali metals are usually discovered in nature. They have highly reactivity at STP conditions (standard temperature and pressure conditions) and easily lose their outermost electron to form positive ions known that have a charge of +1.

Thus, what can determine the extent of reactivity of an alkali metal, is it's ability to lose electrons

Which ion would represent the ion of an element from Group 2A?
ziro4ka [17]

Answer:

E²⁺

Explanation:

The group two contain alkaline earth metals.

There are six elements in group 2A.

Beryllium, Magnesium, calcium, strontium, barium and radium.

All members have two valance electrons.

They lose two valance electrons to complete the octet.

When they lose the two valance electrons they form cation X²⁺.

They react with halogens and form salt such as

MgCl₂, CaCl₂ etc.

Mg²⁺  Cl²⁻₂

The oxidation state of halogens are -1, while the elements of group two A shows +2 that's why two atoms of halogen are combine with one atom of alkaline earth metals and make the compound overall neutral.

All the alkaline earth metals have similar properties.

Answer:

I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

which factor is most responsible for the fact that water is a liquid rather than a gas at room temperature
frosja888 [35]

The answer is Hydrogyn bonding. It keeps the water molocules bonded together and in a liquid state, without it it'd be in a gashious state.
