A) What characteristics of physical properties distinguish metals from nonmetals?

salantis [7]

Answer:

The answer to your question is:

Explanation:

Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.

Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.

Metals are located in the left side of the periodic table

Nonmetals are located in the right side of the periodic table.

Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.

Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.

The overall charge of an atom is ________ if the number of electrons is ________ than the number of protons.

miss Akunina [59]

The overall charge of an atom is positive if the number of electrons is less than the number of protons. Electrons are negatively charged particles while protons are positively charged particles. If there are less electrons as compared to the number of protons in an atom, then naturally the overall charge of the atom would be positive since there are excess protons. Another case would be that the overall charge of an atom is negative if the number of electrons is greater than the number of protons. An atom having more electrons than the number of the protons present would lead to a negative value of the charge since there are excess electrons.

What type(s) of bonding would be expected for each of the following materials: brass (a copper-zinc alloy), rubber, barium sulfi

mr_godi [17]

The force of attraction that results in holding of atoms or ions together in a molecule or crystal is said be bonding. Bond formation can take place by either attraction or transfer of electrons. There are single, double, and triple bonds. There are many types of bonding namely:

Covalent (sharing of electrons takes place).

Ionic (transfer of electrons takes place).

Metallic (ionized atoms of metals and the sea of electrons around them).

Brass (a copper-zinc alloy)

Brass is an alloy of metal that is copper and zinc. Hence, the metallic bonding is present in the brass.

Rubber

It is a polymer whose monomer unit is isoprene, which is a covalent compound. The isoprene units are attached in repeated units to form rubber by covalent bonding.

Barium sulfide ( $BaS$ )

Due to the large electronegativity difference between barium and sulfur, barium sulfide is an ionic compound. Thus, ionic bonding is present in barium sulfide.

Solid xenon

Only xenon atoms are present in solid xenon which are interacted by weak Van der Waal's interactions.

Bronze

Bronze is an alloy of metal that is copper and tin. Hence, the metallic bonding is present in the brass.

Nylon

It is a polymer whose monomer unit is caprolactam, which is a covalent compound. The caprolactam units are attached in repeated units to form nylon by covalent bonding.

Aluminum phosphide ( $AlP$ )

Aluminum phosphide is a covalent compound and thus involves covalent bonding.

Describe in general terms the structure of ionic solids such as nacl

allochka39001 [22]

<span>Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).</span>
