The electron sea model for metals suggest that the valence electrons drift freely around the metal cations.
Answer: B
Explanation
The sea model of electron is used for describing the mechanism of metallic bonding.
The metallic bonding generally occurs between 2 or more metals leading to the formation of alloys.
According to electron sea model, the electrons which contributes to the metallic bond are mostly the valence electrons of the atoms, these valence electrons get de-localized and can move freely around the nuclei of other atoms.
Overall, it seems like nuclei of positive charge is surrounded by sea of negative electrons.
You can know the metal with low reactivity and the metal with high reactivity from the periodic table, as in metals the Chemical reactivity increases by going down a group, because of the farther down group we go the easier of lose and gain of electrons or the easier the electrons to be given or taken, this caused the chemical reactivity be higher.
- and the chemical reactivity decreases as we go across the period because they want to give away valence electrons, they need more energy to get rid of them.
Its hydrogen atom is a high conductor of electricity
It's the first one, but technically water turns to ice if it's 0 C or less.
