magnesium and fluorine will formthe ionic compound, MgF2
SeI4 is polar.When a compound hasno lone pairs2 lone pairs and 4 atoms4 lone pairs and 2 atoms3 lone pairs and 2 atomsit is non-polar. All others are polar.
PBr5 is non-polar because it is a trigonal bipyramid with no unbound pairs.
The correct Lewis structure for a molecule of the compound C2H2 contains an alkyne bond. This is a triple bond between two C atoms. It has a linear bond geometry and no lone pairs.
Eventhough we classify chemical bonds as ionic and covalent,when we get deeper into nature of bonds, we find that what we call an ionic bond has some amount of covalent character and vice versa.So theoritically speaking there's no such thing like nonpolar covalent bond.But if we consider cases of homonuclear diatomic molecules like O2,H2 etc. the electronegativity difference between the two bonded atoms is almost zero and hence there would be an ideal case of equal sharing of electrons by the two atoms in those molecules.Hence it may be called as a nonpolar covalent bond.
The molecular shape of BeF2 is:F-----Be-----FIt is linear, because it has 2 bond pairs and 0 lone pairs.Bond angle (between the 2 Fluorine's is 180)
Metal and Non-metal
Those on opposite sides of the periodic table (ignoring the noble gases of course). Like sodium and cloride (to make table salt).
It`s Diatomic
Sodium and iodine combined together would have the name "sodium iodide". The chemical formula would be NaI.
CO2 is a covalently bonded compound, taking the form of O=C=O, with two pairs of electrons on each oxygen atom. Ionic compounds involve ionic bonds, such as that of NaCl (Na+ and Cl-).
IONIC BOND: The compound formed by completely transporting an electron or a number of electrons is called an ionic compound, and the bond between the elements of the compound is called the ionic bond. EXAMPLE: NaCl is an ionic compound in which the Na atom donates 1 electron to Cl atom to attain stability and thereby to form the compound NaCl. In ionic bond, generally the metals are the electron donors and the nonmetals are the electron acceptors COVALENT BOND: The bond formed by sharing pair(s) of electrons is called covalent bond. In this type of compound, each of the atom shares equal no. of electrons in order to attain stability. A covalent bond can be of three types: single covalent bond, where 1 pair of electrons is shared between the atoms; double covalent bonds, where 2 pairs of electrons are shared; and triple covalent bond, where 3 pairs of electrons are shared.EXAMPLE:N2 molecule is formed by sharing of 3 pairs of electrons, thereby forming a N-N triple bond
Some molecules (not just ionic compounds) always tend to come in pairs. Aluminum oxide for example Al2O3 always comes in a pair Al4O6, the empty electron pairs on the Aluminum making attractive sites for the filled electron pairs on Oxygen to 'stick' to.
Because lithium form a cation and sulfur an anion the lithium sulfide (Li2S) form an ionic compound, a salt.
Yes !
When atoms share electrons in one or more pairs, they form a new compound by covalent bonding.
