Answer from: Kigarya

The correct answer is alkali metals.

Explanation:

For the given options:

Option 1: Halogens

Halogens are the elements which are present in Group 17 of the periodic table. The general electronic configuration for the elements of this group is ns^2np^5 where 'n' is the number of periodic table.

These elements will require 1 electron and thus, will attain -1 oxidation states.

Option 2: Alkaline earth metals

Alkaline earth metals are the elements which are present in Group 2 of the periodic table. The general electronic configuration for the elements of this group is ns^2 where 'n' is the number of periodic table.

These elements will loose 2 electrons and thus, will attain +2 oxidation states.

Option 3: Noble gases

Noble gases are the elements which are present in Group 18 of the periodic table. The general electronic configuration for the elements of this group is ns^2np^6 where 'n' is the number of periodic table.

These elements does not require any electron and thus, will remain as such.

Option 4: Alkali metals

Alkali metals are the elements which are present in Group 1 of the periodic table. The general electronic configuration for the elements of this group is ns^1 where 'n' is the number of periodic table.

These elements will loose 1 electron and thus, will attain +1 oxidation state.

From the above information, the correct answer is alkali metals.

Match the words in the left column to the appropriate blanks in the sentences on the right. (a) this is the law of definite proportions: all samples of a given compound, regardless of their source or how they were prepared, have proportions of their constituent elements. (b) this is the law of conservation of mass: in a reaction, matter is neither created nor destroyed. (c) this is the law of multiple (c) this is the law of multiple blank: when two elements form two different compounds, the masses of element b that combine with 1 g of element a can be expressed as a ratio of small whole-numbers. in this example, the ratio of \rm o from hydrogen peroxide to \rm o from water = 16: 8 \to 2: 1, a small whole-number ratio.: when two elements form two different compounds, the masses of element b that combine with 1 g of element a can be expressed as a ratio of small whole-numbers. in this example, the ratio of o from hydrogen peroxide to o from water = 16: 8 â†’ 2: 1, a small whole-number ratio.
