3 0

Answer:

Compound B is ionic. The electronegativity difference is 2.2, which can be determined by subtracting the electronegativity of Element Y from that of Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.

Hope that helps.

How many electrons in an atom can share the quantum numbers n = 4 and l = 3?
o-na [289]

Answer:

\boxed{\text{14}}

Explanation:

If l = 3, the electrons are in an f subshell.

The number of orbitals with a quantum number l is 2l + 1, so there

are 2×3 + 1 = 7 f orbitals.

Each orbital can hold two electrons, so the f subshell can hold 14 electrons.

\boxed{\textbf{14 electrons}} \text{ can share the quantum numbers n = 4 and l = 3.}

What does the number next to ions signify?
dusya [7]
<span>The number next to the simbol of the element ions (as a superscript) means the number of charges of the ion. For example N (+),, where (+) is a superscript means that the charge of the ion is 1+. S(2-), where (2-) is a superscript, means that the charge of the ion is (2-). OH (-), where (-) is a superscript, means that the charge of OH ion is (1-) . </span>

If two atoms are bonded with a bond energy of 87 kJ, what must be done to break the bond?
SSSSS [86.1K]
I would say the energy has to be decreased by 87 kj because the bonding is held together by 87 kj so removing that should prevent the bonding from taking place or reverse it I believe. In other words, a certain amount of energy is required to hold the bond together and in the absence of that energy, the bonding will not take place.
