the nuclear equation is incomplete. (_{1}^{1}h + _{7}^{15}n\rightarrow?+_{2}^{4}he) what particle completes the equation? (_{6}^{12}mg) (_{5}^{11}b) (_{5}^{11}na) (_{6}^{12}c)

Answer

Explanation:

Step1: Balance mass - number

The sum of mass - numbers on the left - hand side of the nuclear equation is (1 + 15=16). The mass - number of the helium atom ((^4_2He)) on the right - hand side is 4. So the mass - number of the unknown particle is (16 - 4=12).

Step2: Balance atomic - number

The sum of atomic numbers on the left - hand side is (1+7 = 8). The atomic number of the helium atom is 2. So the atomic number of the unknown particle is (8 - 2=6).

Step3: Identify the element

An element with atomic number 6 is carbon (C). So the particle is (^{12}_6C).

Answer:

(^{12}_6C)
