Answer : An atom with 7 protons, 6 neutrons,
and 7 electrons has an atomic mass of 13 amu.
Explanation:
As we are give that,
Number of protons
7
Number of electrons =7
Number of neutrons =6
As we know that,
Atomic number =Number of protons = Number
of electrons =7
Atomic mass = Number of neutrons + Atomic
number
Atomic mass = 6 + 7 = 13 amu
Therefore, the atomic mass is, 13 amu

Answer:
Venus has a much thicker atmosphere
Explanation:
The main reason for Venus having a much higher temperature than Mercury is due to the difference in atmosphere. Venus has a much thicker atmosphere, this extra thickness allows Venus more heat to get trapped, through the greenhouse effect which keeps Venus much warmer than Mercury. If Venus were to lack this atmosphere it would be much colder than the average temperature in Mercury, which is 333 degrees Fahrenheit.
