Which statement best describes the effect of low ionization energies and low electronegativities on metallic bonding? a. The valence electrons are easily delocalized.
b. The valence electrons stay in a single orbital.
c. The valence electrons break free of the crystals.
d. The valence electrons move closer to the nuclei.

Answers

Answer 1

Answer: Answer: The valence electrons are easily delocalized. As the ionization energy increases the energy required to remove the valance electrons from the atom also increases. So the valance electrons move closer to the nuclei. But low ionization energy makes the atom to lose valance electrons much easier.

How does the degree of disorder of a gas compare to that of a liquid or a solid? please explain your answer. this is a chemistry home work.

Answers

Molecules of gases are spaced far apart from each other compared to liquids and solids. This results in greater disorder in gas molecules. Liquid molecules are spaced slightly closer together than gas molecules, so the disorder is less than gas molecules. Solid molecules are the most tightly packed, and often vibrate in position. This gives solid molecules the least disorder.

Which physical property can be measured? color density odor shape

Answers

Which physical property can be measured? color density odor shape

The physical property that can be measured is the density. Color, odor and shape are properties that cannot be measured. They can be only observed through the naked eye and is subject to qualitative measurement.

Explanation:

The balanced equation below represents a molecule of bromine separating into two bromine atoms.Br2-->Br + Br
What occurs during this change?
(1) Energy is absorbed and a bond is formed.
(2) Energy is absorbed and a bond is broken.
(3) Energy is released and a bond is formed.
(4) Energy is released and a bond is broken.

Answers

(4) Energy is released and a bond is broken. This happens because when the bromine molecule splits, the energy that was holding the two atoms together is released.

Answer is: (2) Energy is absorbed and a bond is broken.

This energy is called bond-dissociation energy.

Bond-dissociation energy is the measure of bond strength in a chemical bond.

Bond energy of bromine molecule (sigma bond) is energy needed for breaking up one molecule of bromine into two bromine atoms.

When two bromine atoms (Br) form molecule of bromine (Br₂), than energy is released and bond is formed.

How do the products and reactants of a chemical change compare? The mass of the products is greater than the mass of the reactants because energy is absorbed by the reaction.

The mass of the products equals the mass of the reactants because energy is not absorbed or given off by the reaction.

The mass of the products is less than the mass of the reactants because energy is given off by the reaction.

The mass of the products equals the mass of the reactants because the same atoms are present throughout the reaction

Answers

The right answer for the question that is being asked and shown above is that: "The mass of the products equals the mass of the reactants because the same atoms are present throughout the reaction." -- The products and reactants of a chemical change should be compared
