Question

Which statement correctly describes the bonding in metals? * (1 Point)

A) lattice of negative ions in a sea of electrons

B) lattice of positive ions in a sea of electrons

C) lattice of neutral atoms with delocalised electrons.

D) lattice of negative ions with delocalised electrons.

Answer 1

C) lattice of neutral atoms with delocalised electrons

Step-by-step explanation:

Fact 1: metals are elements and therefore they contain atoms that are electrically neutral

Fact 2: in all atoms, the electrons are delocalised/ are free moving electrons (as the electrons serve their purpose in different forms depending whether you look at it the chemistry way or physics way)

metals are solid and hence they have a lattice structure

(tho at my school we focus on giant ionic lattice structure when explaining based on ionic compounds so i can't guarantee that 'giant ionic lattice structure' and 'lattice structure' are the same, hence i just stick with lattice structure for this explanation ^^)

explanation for other options:

they said negative/positive ions which is not true since atoms are electrically neutral

only when the atoms undergo chemical reactions will they be charged
