Annette [7]

Answer:

82.7 kg

Explanation:

the mass of the boxer remains unchanged, this is because mass is a measure of the quantity of matter in an object irrespective of its location and the gravitational force acting at its location. this means mass is independent of the gravitational acceleration hence it remains the same 82.7 kg. its unit is in kilograms (Kg).

The element Ne, neon, has ____ (number) complete shells having its ____ electrons in second _____.
KatRina [158]

Answer:

2, 8 and shell

Explanation:

Neon as atomic number 10. Since for each shell, electrons equal 2n².

When n = 1, 2n² = 2(1)² = 2

When n = 2, 2n² = 2(2)² = 8

So it fills both the first and second shell with 2 and 8 electrons respectively to achieve its stable atomic state. The rest of the 8 electrons go into the second shell because the first shell has achieved its stable dual configuration of two electrons. The next shell requires a maximum of 8 electrons to achieve stability so, the remaining electrons fill it up to achieve the stable octet configuration.
