Moving down in a group, the electronegativity decreases due to an increase in the distance between the nucleus and the valence electron shell, thereby decreasing the attraction, making the atom have less of an attraction for electrons or protons.
Answer:
Because the neutrons equal the number of protons
Explanation:
So if u have 16 protons u have 16 neutrons

Answer:
V₂ = 651.34 mL
Explanation:
Given data:
Initial volume = 255 mL
Initial pressure = 2.40 atm
Initial temperature = 7°C (7 +273 = 280 K)
Final temperature = 25°C (25 +273 = 298 k)
Final volume = ?
Final pressure = 1 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 2.40 atm × 255 mL × 298 K / 280 K × 1 atm
V₂ = 182376 atm .mL. K / 280 K.atm
V₂ = 651.34 mL
