boron has very small atomic radius.the hypothetical B3+ ion has very small size and hence high charge densities.This value is so high that B3+ ion does not exist.All thecompounds of boron are therefor covalent.Boron has 4 valencce electro n and this gives it a great electron accepting power that is its compound behave as strong lewis acid

When chlorine forms an ionic compound it gains one electron what symbol is used to represent the chloride ion formed in this way?
Cl- This is the symbol of a chlorine ion that gains one electron
6 Write a chemical equation showing the reaction between ammonia and boron trifluoride BF3 in a Lewis acid-base reaction Show how the covalent bond forms?
The reaction between ammonia and boron trifluoride, BF3If you have recently read the page on covalent bonding, you may remember boron trifluoride as a compound which doesn't have a noble gas structure around the boron atom. The boron only has 3 pairs of electrons in its bonding level, whereas there would be room for 4 pairs. BF3 is described as being electron deficient.The lone pair on the nitrogen of an ammonia molecule can be used to overcome that deficiency, and a compound is formed involving a co-ordinate bond.Using lines to represent the bonds, this could be drawn more simply as:The second diagram shows another way that you might find co-ordinate bonds drawn. The nitrogen end of the bond has become positive because the electron pair has moved away from the nitrogen towards the boron - which has therefore become negative. We shan't use this method again - it's more confusing than just using an arrow.
When fluorine atom gains an electron it forms?
When a fluorine atom gains an electron, it forms a negative ion.
Would you find KF2 as a stable compound?
No. Potassium (K) has only one valence electron, so it would only form a 1+ ion, not the 2+ ion needed for KF2. So instead it forms KF.
What is the binary ionic compound of magnesium and chlorine?
Magnesium forms divalent cations and chlorine forms monovalent anions; therefore, the binary compound of magnesium and chloride has the formula MgCl2.
What is the second row nonmetals that forms electron deficient compounds?
boron
What elements can combine with the element boron?
Many elements can combine with Boron although not many compound with Boron in are found on Earth naturally. Here are some more common examples: Barium (Ba) - Forms Barium Borate Calcium (Ca) - Forms Calcium Borate Lithium (Li) - Forms Lithium Borate
When potassium forms a compound with iodine one electron is transferred from the atom to the atom?
Potassium lose an electron (iodine gain this electron) to form potassium iodide, KI.
Why does boron form a tripositive ion?
Boron has an electronic configuration of 1s22s22p1 (it has 5 electrons). In order to reach the stable electron configuration of a noble gas with a completely filled valence shell, boron atom has to lose 3 electrons to obtain a stable duplet structure (i.e. 2 electrons in its first electron shell). After losing 3 electrons, the boron atom forms a B3+ ion, or a so-called tripositive ion.
When chlorine forms an ionic compound it gains one electron what symbol is used to represent the chloride ion formed?
Cl-
What do you call a bond that forms when electrons are transferred from one atom to another?
ionic bond
What are 2 properties of boron?
Boron forms electron poor hydrides that can exist in many different shapes and formulas because of the hydrogen bridges it can form.

Why Only xe forms chemical compound among inert gass?
xe forms chemical compound among inert gass because :Low ionization EnthalpyMore negative electron gain enthalpyamong all the other inert gases.
