Each of the following nuclides is known to undergo radioactive decay by production of a beta particle, 0.1e. write a balanced nuclear equation for each process. (use 'e' for an electron, p' for a positron, and 'n' for a neutron. omit states-of-matter from your answer.) (a) 146c chempad greek (b) 14055cs chempad greek.

(a)   ¹⁴₆ C ⇒         ¹⁴₇ N +  ⁰₋₁ e

(b) ¹⁴⁰₅₅ Cs ⇒  ¹⁴⁰₅₆ Ba + ⁰₋₁ e

(c) ²³⁴₉₀ Th ⇒  ²³⁴₉₁ Pa + ⁰₋₁ e

Explanation:

In a beta decay the nuclide emits a beta particle which are high enery electrons. The number of neutrons decreases by one and the atomic number increases also by one moving the nuclide one place to the right in the periodic table. The mass of the nuclide does not change since the mass of electron is negligible compared to the proton and neutron.

(b) ¹⁴⁰₅₅ Cs ⇒  ¹⁴⁰₅₆ Ba + ⁰₋₁ e

(c) ²³⁴₉₀ Th ⇒  ²³⁴₉₁ Pa + ⁰₋₁ e

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
