Ответ:
Silicon has 14 protons Potassium has 19 electrons The neutrons are equal to the mass number minus the atomic number. Or the big number minus the small number on the periodic table. hydrogen 1 does not have a neutron.
iron =56 -26 for 30 neutrons in the nucleus
Chlorine 17 protons and 17 electrons. 18 or 19 neutrons on average.

The temperature of the town will be 15°F.
The equation showing the final temperature after drop say x degrees can be written as:
Explanation:
The current temperature in our town = T = 31°F
Temperature drop suggested by radio announcer = 15°
Temperature of the town after temperature drop = T'
The equation showing the final temperature after drop say x degrees can be written as:
