across a period, how does the electronegativity of a nonmetal affect the acidity of its binary hydride
goblinko [34]
1) Across the period as one moves from left to right, atomic size decreases.

2) Consider 3rd period elements containing non-metal i.e Si, P, S and Cl.

3) Here, atomic radius of these elements are in following order Si>P>S>Cl.

4) However, electronegative of these elements increases as we move from left to right

5) Thus, the corresponding hydrides have higher electro-negativity difference,as one moves from left to right.

6) Due to this, bond polarity increases from left to right,

7) Increase in bond polarity, results in increasing proton donating capability.

8) Therefore, acidity increases as one moves along the period.

Which statement best describes what is happening in this model?
lapo4ka [179]

The answer is (C) The electrons are moving easily between the nuclei of metal atoms.

The explanation:

-The electrons then move freely throughout the space between the atomic nuclei. ... Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current. Metals are ductile and malleable because local bonds can be easily broken and reformed.

1-Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current.

2-Metals are ductile and malleable because local bonds can be easily broken and reformed.

3-Metals are shiny. Light cannot penetrate their surface; the photons simply reflect off the metal surface. However, there is an upper limit to the frequency of light at which the photons are reflected.
