Answer:
Shorter revolution times, Made of rock, No rings
Explanation:
want more facts? Here u go!
The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planets (Figure below). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets.
All of the inner planets were geologically active at one time. They are all made of cooled igneous rock with inner iron cores. Earth has one big, round moon, while Mars has two very small, irregular moons. Mercury and Venus do not have moons.
Answer:
The law of conservation of mass
Explanation:
The law of conservation of mass
Answer:
One mole of a substance is equal to 6.022 × 10²³ units of that substance (atoms, molecules, or ions)
Explanation:
This number is Avogadro's number. The concept of the mole can be used to convert between mass and number of particles. its used to compare very large numbers.
Answer:
Protons and Neutrons
Explanation:
The sum of number of protons and the number of neutrons is equal to the mass of an element. Mathematically, it can be given as :
M = P + N
Also, the atomic mass can be calculated by the sum of the element's isotopes as isotopes have slightly different mass numbers.
Hence, protons and neutrons add together to determine the atomic mass.
