An atom of an alkaline earth metal reacts with another element to form a compound. which element mostly likely combined with the alkaline metal?
a) iron
b) neon
c) oxygen
d) sodium

oxygen

Explanation:

An ionic compound is formed when one element completely transfers its valence electron to another element.

The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.

As alkaline earth metal can lose two electrons, it will combine with an element which can gain electrons.

Thus alkaline earth metal MOSTLY LIKELY combine with oxygen.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
