When an atomic nucleus emits an alpha particle it decay into an atom with atomic number 2 less and mass number 4 less. Thus Thorium 230 decay as follows.
230 90Th -------> 226 88Th + 4 2 He
thorium is in the atomic number 90 thus it during alpha decay it reduces to atomic number 88 while its 230 mass number reduces to 226
Answer:
-195.8 °C = 77.35 K = -320.44 °F
Explanation:
Temperature is commonly measured in following three scales;
1) Kelvin
2) Fahrenheit<span>
3) </span>Celsius<span>
Other scales are Rankine, Romer, Newton, Delisle e.t.c
Temperature given is -195.8 </span>°C. Degree Celsius is related to Kelvin and Fahrenheit as follow,
Celcius to Kelvin;
K = °C + 273.15
So,
K = -195.8 + 273.15
K = 77.35
Celcius to Fahrenheit;
°F = °C × 9/5 + 32
So,
°F = -195.8 × 9/5 + 32
°F = -320.44
The bonding of two atoms will most likely occur if A. a more stable state can result from the union.
Otherwise, there would be no point in making two atoms bond.
