The condensed electron configuration of this element might be is 8s^25g^6. The electronic configuration is a depiction of the distributions of different or various physical elements such as atoms, molecules, and also the electrons. The electronic configuration is said to be like a code that explains the relationships of electrons.

Answer:

5g2 6f2 7d1 8s2 8p1

Explanation:

The full electrons configuration for this element would be:

1s2 2s2 2p6   3s2 3p6 3d10   4s2 4p6 4d10 4f14   5s2 5p6 5d10 5f14 5g2    6s2 6p6 6d10 6f2    7s2 7p6 7d1   8s2 8p1

This configuration explains the electron orbit levels and the arrangement of all the electrons for that element. Each element has its own electron configuration. The configuration shown for element-126 is only a prediction, as the element is not naturally occurring on the planet.

How does the modern periodic table arrange elements?
Norma-Jean [14]
<span>The </span>elements are arranged<span> in order of increasing atomic number. Vertical columns(called groups) contain </span>elements with similar properties. Horizontal rows called periods elements with<span> the same number of atomic orbitals(That's why Hydrogen and Helium are separated from the rest of the table).

Which of these is not a covalent molecule?<br> 1. F2<br> 2. CO<br> 3. LiF<br> 4. NH3
beks73 [17]

LiF or lithium fluoride is the non covalent molecule or ionic compound.

Option 3.

<h3><u>Explanation:</u></h3>

Covalent molecules are those molecules which do have actual bonds between the atoms present in the molecule by sharing of the electrons. But in ionic molecules, there's no actual bonds between the atoms, but the oppositely charged ions are attracted towards each other by means of electrostatic force of attraction.

The molecules that are formed by the atoms with high electronegativity and electropositivity are actually ionic because the atoms with high electronegativity are able to actually gain electron readily and the atoms with high electropositivity are actually ready to give the electrons to the electronegative elements.

Lithium is highly electropositive and fluoride is highly electronegative. So they establish an ionic bond. But other molecules like fluorine molecule has both the electronegative elements, Carbon monoxide has carbon which isn't electropositive highly, and ammonia has hydrogen which isn't electropositive.

So lithium fluoride is the ionic compound.

Why are tigers and lions able to mate to produce cubs,but those cubs would not be able to go on to produce any off spring
Sveta_85 [38]

Answer:

Tigers and lions able to mate to produce cubs,but those cubs would not be able to go on to produce any off spring because their sex chromosomes do not match.

Explanation:

  • Tigers and lions mate to produce ligers and tilons but they do not produce viable sperms or egg.
  • In an organism there are two copies of chromosomes present in the somatic cells.
  • But in case of sex cells they receive each set from mother and father. which they duplicate and divide during formation of gametes via meiosis.
  • in such case if the sets are recieved from two different species then after pairing a mismatch will occur in the gene loci.For example, a eye colour gene may correspond to a paw length gene.
  • Thus the gametes when produced will not be viable.

The pka of hf is 3.2 determine the pkb of hf?
Julli [10]

Well, first we must remember that

pK_{a}+pK_{b}=14

This is because

K_{a}*K_{b}=10^{-14}

-log(K_{a}*K_{b})=-log(10^{-14})\\-logK_{a}+-logK_{b}=-log(10^{-14})\\pK_{a}+pK_{b}=14

So then

pK_{b}=14-pK_{a}=14-3.2=1.8
