Answer:

Ferromagnetic materials make the magnet stronger than non-ferromagnetic materials like paper, wood, or air. A wider nail will make the magnet stronger. Making the nail longer will not make the magnet stronger, unless you also add more turns to the coil.

Answer:

I believe- If there is more metal for the magnet to reach for, then the strength will grow but it may be harder to pick up off of a surface depending on the weight of the nail. If it is a light nail, it would be more efficient for a quick result in having the magnet to pick it up

Which of these solid compounds are most likely to have its dominant bonding mechanism as covalent? (Select all that are true.)
I am Lyosha [343]

The compounds that have covalent bonding as their dominant bonding scheme are diamond and silica.

A covalent bond is formed between two nonmetals. Usually, when two nonmetals combine, electrons are shared between the two atoms involved in the bond.

Now, the solids diamond and silica are predominantly covalent solids. The atoms that combine in diamond are carbon atoms(nonmetals) while the atoms that combine in silica are silicon and oxygen (nonmetals also)

Hence, diamond and silica both have covalent bonding as their dominant bonding scheme.

Answer: Alkali metals, group 1

Explanation: Group 1 means 1 valence electron. This group is called alkali metals, which indicates that it is a metal. They are highly reactive because only 1 electron needs to move to bond with something (since it only has 1 valence electron)
