As you move down the periodic table, atomic size increases (due to the number of electron shells of an atom increasing). So in Group 1, H has the smallest atomic size, while Fr has the largest.

Ionization energy tends to decrease as you go down a group, and increase as you go from left to right on the periodic table. (As you go down, the atomic size/radius increases, so the outermost electrons are held less tightly to the nucleus, causing a lower ionization energy.)

Electronegativity relates to ionization energy. Elements with a higher ionization energy will have higher electronegativity. Therefore, as you move down the periodic table, electronegativity decreases, while as you move from left to right on the periodic table, electronegativity increases.

Which molecule has the greatest difference in electronegativity (DE) between the two different elements? A. CO_2 B. H_2S C. NH_3
Natalka [10]

Answer:

Water has the greatest ΔEN

ΔEN H₂O → 3.4 - 2.1 = 1.3   Option D.

Explanation:

We should find the Electronegativity data in the Periodic table for all the elements:

C : 2.6

O: 3.4

H: 2.1

S: 2.6

N: 3.0

a. ΔEN CO₂ → 3.4 - 2.6 = 0.4

b. ΔEN H₂S → 2.6 - 2.1 = 0.5

c. ΔEN NH₃ → 3 - 2.1= 0.9

d. ΔEN H₂O → 3.4 - 2.1 = 1.3

The diagram below shows the different phase transitions that occur in matter.
solmaris [256]

Answer:

# 5

Explanation:

The question describes silver being "poured" into a mold and cools to become a solid bar. This is the phase of liquid to solid. When a element cools down below it's freezing points to become a solid.

<u>Liquid to Solid Definition:</u>

Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. All known liquids, except helium, freeze when the temperature is low enough.
