Which element has 3 electron shells and 7 electrons in its outermost shell?

Which element has 3 electron shells and 7 electrons in its outermost shell?

Example 1: Fluorine, chlorine, bromine, and iodine each have 7 electrons in their outermost shell.

Which of the following atoms can have more than 8 outermost electrons?

Answer. Answer: Only atoms with empty d orbital can achieve more than 8 electrons in a covalent bond. The electronic configuration of sulphur in ground state is [Ne]3s2 3p4.

When forming covalent bonds which atom can have more than 8 electrons?

Due to presence of vacant d-orbital excitation occurs in Cl-atom and it can have more than eight valence electrons when it is forming hypervalent compound like HClO4.

When forming covalent bonds which atom can have more than 8 valence electrons?

Meallic elements can definiely have more than eight valence electrons, however they do not tend to form covalent bonds. Therefore the maximum number of covalent bonds should be said to be 7, with the exception of some noble gases since they are very stable by themselves.

Which species contains only covalent bonds?

Explanation: …and only the one distillable liquid. Aluminum fluoride, ammonium nitrate, and potassium dichromate are made of discrete ions…and the parent ions are easy to assess from the formulae: Al3+ ; Al3+,3×F− ; NH+4,NO−3 ; 2×K+,Cr2O2−7 .

Does SF6 contain only covalent bonds?

– Sulfur hexa fluoride (SF6) is a completely covalent compound. – There is no ionic bond present in it as there is no transfer of electrons. – It contains 6 sulfur – fluorine (S – F) bonds that are arranged in an octahedral manner. – Hence, it contains only 6 covalent bonds.

Which of the following compounds contains both ionic and covalent bonds?

Sodium nitrate is a compound with both ionic and covalent bonds.

Is SF6 covalent or ionic?

Answer: SF6 (or sulfur hexafluoride) is a covalent compound because both sulfur and fluorine are nonmetal elements.

Is MGO ionic?

Magnesium oxide is considered ionic.

Is clf3 ionic?

See; CF3 (chlorine trifluoride) is an interhalogen compound( compounds made between two different kind of halogen) and they are much reactive than the parent halogen( eg xx’ then xx’ is more reactive than x and x’) and due to electronegative differences between both the atoms therefore they are ionic…

Is SnCl4 ionic?

As SnCl4 show Sn 4+ oxidation state and tends to have higher positive charge and its size is smaller than Sn 2+ i.e Sn4 + polarise Cl- more than the Sn2+ ion i.e SnCl4 is covalent in nature. Hence SnCl2 is ionic whereas SnCl4 is covalent.

Why is SnCl2 ionic?

even though SnCl2 completes its octet at the tin centres and is polymeric in nature,,,,,SnCl2 in solid state does not consist of a repeating lattice of distinct Sn2+ cations and Cl- anions… hence it is an ionic compound,,,.

Which is more ionic SnCl2 or pbcl2?

Answer. As we go down the group, +2 oxidation state becomes more favorable and stable. Since Pb is more down the group than Sn, it’s stable with +2 oxidation state where Sn can exhibit both +2&+4 but +4 is more stable due to which SnCl2 is a strong reducing agent.

Which of the following is more ionic?

So KCl is more ionic.
