Answer:
B. They are the electrons that interact with other atoms.
Explanation:
Valence electrons are the electrons in the outermost shell of an atom. These electrons are used by atoms to form bonds with other atoms during chemical bonding.
- So, the basis by which atoms interacts with one another is through the valence electrons.
- Without the valence electrons, atomic combination to form compounds would not be possible.
- Valence electrons are the most loosely held electrons and they have the lowest ionization energy.
The Earth's radius is 6371 km. So that's our distance from the center when we're on the surface.
The Shuttle astronaut's distance from the center, when s/he's in orbit, is 330 km greater ... that's 6701 km.
The force of gravity is inversely proportional to the distance between the center of the Earth and the center of the astronaut. So, in orbit, it's
(6371/6701)^2 = 90.4 %
of its value on the surface.
Answer:
friction
Explanation:
the road is the pathway for the vehicle so the tures create friction to stay sturdie
