Say that you will be on Erasmus in the university for the coming academic year. Say you donât know anybody in Caceres and ask if he/she could give you some advice about accommodation.Â
Say that you would prefer to live near the university because last year you lived in the outskirts of Dublin and really didnât like itÂ
PreferirĂa vivir cerca de la universidad porque el ano pasado, vivĂ en las afueras de DublĂn y no me gustĂł.Â

Well, you spent too much time travelling because it was very far from everything. Say that if you could spend that time studying you would be able to get good grades. Â
Say thatâs not far and the climate is much better than in Ireland so you will consider all areas even though you would prefer to live in the city centre.Â
Compound: two or more different elements combined together chemically
Octet Rule: when bonding occurs, atoms tend to reach an electron arrangement with 8 electrons in the outermost energy level
Ion: a charged atom or group of atoms
Ionic bonding: the force of attraction between oppositely charged ions in a compound. Formed by the complete transfer of an electron from one atom to another
molecule: a group of atoms joined together, the smallest particle of an element with can exist independently
valency: the number of atoms of hydrogen (or any monovalent element) with which each atom of the element combines
Transition metals have variable valency, they can lose different numbers of electrons
covalent bonding is when electrons are shared, not transferred like ionic bonding
a single bond is when one pair of electrons is shared, double = 2 pairs, triple = 3 pairs
