Which of the fallowing scientific claims about the bond in the molecular compound HF is most likely to be true?

DENIUS [597]

The bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

The term polar means that there is separation of charges, the bonds will be the more polar the greater the difference in electronegativity between the bonded atoms.

In hydrogen fluoride, for example, F is more electronegative than H because its nucleus, with 9 positive charges, attracts e-shares with H more strongly than the nucleus of H, with only one positive charge.

Therefore, the e- shared by covalence will be closer to F than to H and the molecule forms a permanent dipole.

Therefore, we can conclude that the bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

Write the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by each:

Sladkaya [172]

Answer:

Part A:

Charge is $P^{3-}$

Configuration is $1s^2 2s^22p^63s^23p^6$

Part B:

Charge is $Mg^{2+}$

Configuration is $1s^2 2s^22p^6$

Part C:

Charge is $Se^{2-}$

Configuration is $1s^2 2s^22p^63s^23p^64s^23d^{10}4p^6$

Explanation:

Monatomic ions:

These ions consist of only one atom. If they have more than one atom then they are poly atomic ions.

Examples of Mono Atomic ions: $Na^+, Cl^-, Ca^2^+$

Part A:

For P:

Phosphorous (P) has 15 electrons so it require 3 more electrons to stabilize itself.

Charge is $P^{3-}$

Full ground-state electron configuration of the mono atomic ion:

$1s^2 2s^22p^63s^23p^6$

Part B:

For Mg:

Magnesium (Mg) has 12 electrons so it requires 2 electrons to lose to achieve stable configuration.

Charge is $Mg^{2+}$

Full ground-state electron configuration of the mono atomic ion:

$1s^2 2s^22p^6$

Part C:

For Se:

Selenium (Se) has 34 electrons and requires two electrons to be stable.

Charge is $Se^{2-}$

Full ground-state electron configuration of the mono atomic ion:

$1s^2 2s^22p^63s^23p^64s^23d^{10}4p^6$
