17. The correct arrangement of the following elements in order of
tatuchka [14]

Answer:

Got your back

Explanation:

If the ions derived from different atoms are isoelectronic species, then they all have same number of electrons in their electronic shells and will have got same electronic configuration but their nuclear charge will differ because of their difference in number of protons in the nucleus. With increase in number of protons in the nucleus the electrons are more attracted towards nucleus thereby causing the decrease in ionic radius. On this principle our problem will be solved

The given ions are

7N-3

→no. of proton

=7

and

no of electron

=10

8O-2

→

no. of proton

=8

and

no of electron

=10

9F-→

no. of proton=9

and no of electron=10

11Na→

no. of proton=11

and no of electron=10

12 Mg-3→

no. of proton=12 and

no of electron=10

Hence the increasing order of ionic radius is

12Mg-3<11Na+<9F-<8O-2<7N-3

To rmember ->For isoelectronic species lower the nuclear charge higher the radius

Are you friend with Nitrogen and Oxygen
Oduvanchick [21]

Nitrogen and oxygen do not react at ambient temperature. At high temperatures they have endothermic reactions and produces various oxides of nitrogen.

Explanation:

The difference between nitrogen and oxygen is the nitrogen has seven protons and seven electrons surrounding the nucleus. Whereas the oxygen has eight protons and electrons.

The atoms combines with one another to form molecules. The nitrogen is a inert, colorless gas with no smell or taste, its harmless to human beings.

The oxygen and nitrogen are abundant gases in the atmosphere and have similar physical properties. The oxygen (O2) is twice as soluble in water as nitrogen (N2).
