Answer:
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
Answer is (1) - N
<em>Explanation:</em>
I think the given chart is electronegativity chart.
Electronegativity is a
value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is
high, then the attraction to the electrons is high unless the attraction to the
electrons is low. </u>
Electronegativity increases from left to right of the periodic table and decreases from up to down.
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).
The electronegativity values for given atoms are
N - 3.0
Na - 0.9
P - 2.1
Pt - 2.2

Answer:
The term dielectric makes reference to materials that are insulators (the charges in the material does not flow freely and for this reason an insulator material cannot conduce electricity). BUT if we applied this material in an electric field they can be polarized.
Dielectric Constant: It is also defined as a relative permittivity and it is the amount of charge required to produce one unit of electric flux( electric field in a surface) in a given medium.
it is typically denoted as Epsilon (ε)
and its formula is: ε = ε(ω) /ε(0)
where:
ε(ω) = the frequency-dependent permittivity of the material
ε(0) = the dielectric constant value in vacuum
Dielectric Constant values:
- For vacuum is always 1
- for water depending on the temperature can be 87.9 at 0º C, 80.2 at 20º C and 55.5 at 100º C.
Answer:
2.5 atm
Explanation:
P2 = 1.2 atm x 2.65 L x 345 K / 1.5 L x 298 K
Esto debería ser igual...
2.45 atm (personajes importantes)
