What are the atomic number and mass number for the carbon isotope with seven neutrons?

The answer to your question is:  

atomic number (Z): 6

mass number (A) : 13

Explanation:

Carbon has an atomic number of 6 and a mass number of 12,

Mass number = # protons + # neutrons

12 = 6 + # neutrons

#neutrons = 12 - 6 = 6

For the carbon isotope the atomic number does not change is still 6

 13 = 6 + # neutrons

# neutrons = 13 - 6

# neutrons = 7

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

ugh fiel iente of insistí is did kiwis jaj
