The absolute value of the melting point of neon greater than the absolute value of the melting point of hydrogen.
<u>Step-by-step explanation:</u>
In positive numbers, when the number gets larger then it is considered to be the greatest number.
for example: 20 > 5.
Meanwhile, For negative numbers, when the number gets larger then it is considered to be the smallest.
For example: -21 > - 40.
From the given table, we are given with the values of Melting point:
Hydrogen= -259.
Neon = -248.
Oxygen = -218.
We have to compare the melting points of hydrogen and neon,
⇒ - 248 > - 259.
Thus the melting point of the neon is greater than the melting point of the hydrogen.
