Beryllium, Be _____ in benzene (inorganic solvent), other element in group 2 ______. Example, BeCl2 ______ in benzene.

soluble, insoluble, cannot dissolve

insoluble, soluble, cannot dissolve

Electronegativity is basically a chemical property that describes how an atom can ________ with an electron in very well way. Values that electronegativity run from _______. As we all know electronegativity is used to assume the bonding between atoms and also see that they are ________, we can also predict that the result of molecules will be _______.

attract, 0 to 4, ionic or covalent, polar or non-polar

repulsions, 0 to 4, polar or non-polar, ionic or covalent

attract, 0 to 4, polar or non-polar, ionic or covalent

Be, beryllium's valence electron is very ______ to nucleus. Be, beryllium more ________, ________, its electron _____ to be released during reactions.

near, electronegative, less reactive, hard

far, electropositive, more reactive, easy

far, electronegative, less reactive, hard

near, electropositive, less reactive, hard

Reactivity increases from Be to Ba, when down group 2 because ....

Valence electrons further from nucleus, the large shielding effect, weaker the nuclear pull towards the electrons, easier for metal to lose electrons.

Valence electrons near from nucleus, the small shielding effect, stronger the nuclear pull towards the electrons, hard for metal to lose electrons.

Melting point of:<br />BeCl2 = 399'C<br />BaCl2 = 962'C<br />Why?

BeCl2, simple molecular structure molecules held by weak van der Waals forces.

BeCl2, giant ionic structure, ions held by strong ionic bonds.

BaCl2, simple molecular structure molecules held by weak van der Waals forces.
