Atoms with a low electronegativity, like lithium, have a weak attractive force

for electrons because:

Atoms with a low electronegativity, like lithium, have a weak attractive force for electrons because they have few valence electrons and aren't close to having eight valence electrons.

Explanation:

Just did this question, guessed, and somehow got it right. Hope this helps!!!

answer: he got 23

explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
