Which of the following statement is true about metalic bond?
Formation of metallic bond does not involve transfer or sharing of electrons between atoms.
Formation of metallic bond involves sharing of electrons like the formation of covalent bond.
Formation of metallic bond involves transfer of electrons from a metal to a non-metal atom.

What is the meaning of Dative Bond?
a covalent bond between two atoms where one of the atoms provides both electrons that form the bond.
a covalent bond between two atoms where both of the atoms provides both electrons that form the bond.
same with an ionic bond
not exist
What is the basis of hydrogen bond?
Attraction forces between hydrogen atom bonded with another hydrogen atom
Attraction forces between hydrogen atom bonded with a high electronegativity atom (F, O, N)
A type of covalent bond in which two electrons derived from one atom.
Attraction forces between hydrogen atom with another hydrogen atom of another molecule
How can dative bond form in hydroxonium ion H3O+?
The pair of electrons not involved in covalent bond in water molecule, H2O will be shared with hydrogen ion H+
Water molecule, H2O and hydrogen ion, H+ will each share one electron
Water molecule, H2O and hydrogen ion, H+ will each share two electrons
The information below is about elements W and X.
- Element W has a proton number of 13.
- Element X is located in Group 17 of the Periodic Table.
Element W reacts with element X to form a compound. The chemical equation for this reaction is ___________.
2W +X2 → 2WX
2W + 3X2 → 2WX3
W +2X → WX2
2W + X → W2X
Which is not true of the chemical bond shown on the diagram?
An electron from Na is transferred to Cl.
The bond is ionic since electron is shared by the two atoms.
A metal and a non-metal are involved in the bonding.
Na will become positively charged and Cl will be negatively charged.
Which two statements are correct about the figure shown?
It is a covalent bond.
Hydrogen atoms loss electrons and Carbon gains the atoms.
It happens on metal and on another non-metal.
The valence electrons are shared by both atoms.
