Answer:
B. A covalent bond has a lower potential energy than the two separate atoms.
Explanation:
<em>Identify the correct statement. </em>
<em>A. It is not possible for two atoms to share more than two electrons.</em> FALSE. Atoms also can share 4 electrons (double bond) or 6 electrons (triple bond).
<em>B. A covalent bond has a lower potential energy than the two separate atoms.</em> TRUE.
<em>C. Single bonds are shorter than double bonds.</em> FALSE. Single bonds are longer than double bonds.
<em>D. A covalent bond is formed through the transfer of electrons from one atom to another.</em> FALSE. In covalent bonds, electrons are shared, not transferred from one atom to another.
<em>E. A pair of electrons involved in a covalent bond are sometimes referred to as lone pairs.</em> FALSE. Lone pairs are those that do not participate in a bond.
Answer:
Magnesium has an outer energy level of n=3 with two electrons in in its energy level. Therefor Magnesium has 2 valance electrons.
Explanation:
Answer:
mass of substance =50.4 g
Explanation:
Using the density formula;
Density = mass of substance / volume of substance
Therefore, making mass subject of the density formula,
mass of substance = volume of substance / density of substance
volume of substance = 60.5 mL, density = 1.20 g/mL ( since common units of density is either g/cm³ or g/mL)
mass of the substance = 60.5 mL / 1.20 g/mL
mass of substance = 50.4 g
Answer:
True
Explanation:
No, a single particle cannot have a temperature at all, because temperature is a property of a large number of particles.- this is not my own words the website I got it from is https://www.quora.com/Can-a-single-particle-have-any-temperature
