How are covalent bonds explained?

When the atom shares an electron with an another atom

When one atom takes the other atom's electron

When the neutrons leave the nucleus

Why do atoms share electrons?

To attain the electron configuration of a noble gas.

To become ions and take a charge

What is the arrangemnt for giant covalent substance?

Massive structures of atoms covalently bonded together

Small groups of atoms covalently bonded together by sharing electrons

Close packed array of atoms with "sea" of free moving electrons.

+ve ion and -ve ion formed via transferring of electrons held together in giant lattice with strong electrostatic interactions.

Why are simple covalent molecules gases or liquids at room temperature?

weak intermolecular forces between molecules

strong electrostatic attraction between ions

What explains the very high melting and boiling point of water

Strong hydrogen bonds between water molecules

Strong dipole-dipole bonds between water molecules

Dispersion forces which are present in all molecules

Asymmetrical shape of the polar bonds.

Which substance has the weakest intermolecular forces?

Substance C, boiling point of 25 °C

Substance A, boiling point of 75 °C

Substance B, boiling point of 105 °C

Substance d, boiling point of 45 °C

a coordinate covalent bond

a covalent bond in which one of the atoms provides all the shared electrons

where each atom shares some of the electrons

What is the basis of a metallic bond?

the attraction between positive metal ions and free floating electrons.

the attraction of neutral metal atoms.

the attraction between protons and neutrons.

the attraction between positive metal ions and interlocking electrons.

In metals, the valence electrons are considered to be

shared by all surrounding atoms.

attached to particular positive ions.

Electronegativity is...

how good an atom is at attracting electrons

the ability of an atom to lose electrons

the energy required to remove an electron from a specific atom

how easy it is to make friends.
