My name is Ann [436]

Answer:

N- 1s2 2s2 2p3

Mg- 1s2 2s2 2p6 3s2

O- 1s2 2s2 2p4

F- 1s2 2s2 2p5

Al-1s2 2s2 2p6 3s2 3p1

Explanation:

Order of decreasing atomic radius

Mg,Al, N,O,F

Order of increasing ionization energy

Mg,Al, N,O,F

Reason:

Atomic radius decreases with increase in nonmetallic character. Looking at the electronic configurations, as effective nuclear charge increases, the atom becomes smaller and the attractive force between the nucleus and the outermost electrons increases. Hence, the radius of the atom decreases and ionization energy increases. Note that the addition of more orbital electrons implies addition of more nuclear charge since the both must exactly balance for the atom to remain electrically neutral. The more the electrons in the outermost shell, the higher the first ionization energy.

The metals will lose electrons while the non metals will gain electrons in order to attain octet structure.

An ion can be cation (positively charged) or anion (negatively charged).

Cations attain octet structure (8) by losing electron(s) while anions become stable or attains octet structure (8) by gaining electron(s).

The remaining elements are completed as follows to attain octet structure;

<u>Element</u>--<u>valence electron</u>--<u>electrons to gain</u>--<u>electrons to lose</u>--<u>ion formed</u>

O ------------ 6 ----------------------  2 ------------------------  none -------------- O^{2-}

Ca --------   2 ----------------------- none ---------------------- 2 ------------------ Ca^{2+}

Br ----------- 7 ---------------------     1 ------------------------ none --------------- Br^{-}

S ------------ 6 -----------------------  2 ------------------------ none --------------- S^{2-}

Cl ------------ 7 -----------------------  1 ------------------------ none ----------------Cl^{-}

K -------------- 1 ----------------------- none ----------------------- 1 ------------------ K^{+}

Mg ------------ 2 ---------------------- none ---------------------- 2 ---------------- Mg^{2+}

Be ------------- 2 ---------------------- none ---------------------- 2 ---------------- Be^{2+}

Which of the following laws is NOT explained by Dalton's atomic theory? A.the law of conservation of mass B. the periodic law C.
zysi [14]

B. the periodic law

Explanation:

The periodic law was not explained by the Dalton's atomic theory.

The periodic law was first postulated by Dimitry Mendeleef and Lothar Meyer around 1869 where they independently arrived at the periodic table or chart.

  • The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
  • The modern periodic law was restated by Henry Moseley in the early 1900s. He changed the basis of the law to atomic number.
  • The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".

The laws of conservation of mass, multiple proportions and definite proportions are all explained by the Dalton's atomic theory.
