Misha Larkins [42]

Answer:

R aluminium = 2.63x10^-6 Ω*cm

Rcopper = 1.7 x10^-6 Ω*cm

I would use Cu as interconnections in advanced CMOS nodes.

Explanation:

the conductivity formula equals:

σ = n*g*u

n = carrier concentration

u = mobility

g = charge of carrier

The resistivity is equal to:

R = 1/σ

For the aluminium, we have:

g = 1.602x10^-19 C

R = 1/(1.98x10^23 * 1.602x10^-19 * 12 = 2.63x10^-6 Ω*cm

For copper:

R = 1/(8.5x10^22 * 1.602x10^-19 * 43.2) = 1.7 x10^-6 Ω*cm

According to the calculations found for both resistivities, I would use Cu as interconnections in advanced CMOS nodes, since copper has a lower resistivity and therefore, copper conducts electricity better.

Harman [31]
Halogens are a group of elements consisting of Fluorine, Chlorine, Bromine, Iodine and Astatine. In their ionic form, they have a superscript of -1, for example, chloride ion is Cl-1. These means that they readily accept one electron in order to achieve the Octet rule. The Octet rule states that each atom must contain 8 electrons in their valence shell for it to be stable. The most stable set of elements are the noble gases. Because they already fulfill the Octet rule, they no longer take part in reactions. Halogens are also very electronegative, meaning, they attract more electrons toward them. This is also a consequence of the Octet rule.

From the choices, the answers would be:
<span>they require only one electron to complete their outer shell
they have a high electronegativity</span>
