Without consulting Figure 28 or Table 22, determine whether each of the following electron configurations is an inert gas,a halo
Anna [14]

This is an incomplete question, here is a complete question.

Determine whether each of the following electron configurations is an inert gas, a halogen, an alkali metal, an alkaline earth metal, or a transition metal. Justify your choices.

(a) 1s^22s^22p^63s^23p^5

(b) 1s^22s^22p^63s^23p^63d^74s^2

(c) 1s^22s^22p^63s^23p^63d^{10}4s^24p^6

(d) 1s^22s^22p^63s^23p^64s^1

(e) 1s^22s^22p^63s^23p^63d^24s^2

(f) 1s^22s^22p^63s^2

Answer :

(a) 1s^22s^22p^63s^23p^5   → Halogen

(b) 1s^22s^22p^63s^23p^63d^74s^2    → Transition metal

(c) 1s^22s^22p^63s^23p^63d^{10}4s^24p^6   → Transition metal

(d) 1s^22s^22p^63s^23p^64s^1   → Halogen metal

(e) 1s^22s^22p^63s^23p^63d^24s^2     → Transition metal

(f) 1s^22s^22p^63s^2   → Alkaline earth metal

Explanation :

Inert gas : These are the gases which lie in group 18.

Their general electronic configuration is: ns^2np^6 where n is the outermost shell.

Halogen : These are the elements which lie in group 17.

Their general electronic configuration is: ns^2np^5 where n is the outermost shell.

An alkali metal : These are the elements which lie in group 1.

Their general electronic configuration is: ns^1 where n is the outermost shell.

An alkaline earth metal : These are the elements which lie in group 2.

Their general electronic configuration is: ns^2 where n is the outermost shell.

Transition elements : They are the elements which lie between 's' and 'p' block elements. These are the elements which lie in group 3 to 12. The valence electrons of these elements enter d-orbital.

Their general electronic configuration is:  where n is the outermost shell.

(a) 1s^22s^22p^63s^23p^5

The element having this electronic configuration belongs to the halogen family.

(b) 1s^22s^22p^63s^23p^63d^74s^2

The element having this electronic configuration belongs to the transition family.

(c) 1s^22s^22p^63s^23p^63d^{10}4s^24p^6

The element having this electronic configuration belongs to the transition family.

(d) 1s^22s^22p^63s^23p^64s^1

The element having this electronic configuration belongs to the halogen family.

(e) 1s^22s^22p^63s^23p^63d^24s^2

The element having this electronic configuration belongs to the transition family.

(f) 1s^22s^22p^63s^2

The element having this electronic configuration belongs to the an alkaline earth metal.

What is the molarity of the two solutions <br> 0.150 mol of NaOH in 1.80 L of solution
padilas [110]
1 mole of MgS = 24.3 + 32.1 = 56.4 g

35.1 g MgS x 1 mol / 56.4 g = 0.622 mol

M = 0.622 mol / 0.835 L = 0.745 mol/L
