Question

in carbons Bh unit is replaced by​

Answer 1

I can't understand your question

Answer 2

Carbon-12 replaced by Bh, Carbon-14 atoms have nuclei that are unstable. C-14 atoms will undergo alpha decay and produce atoms of N-14. That is called Carbon dating. And Bh is a short-lived radioactive element that does not occur in nature.

Explanation:

• One atomic mass unit is defined as one-twelfth of the mass of one carbon - 12 atom.

• Carbon - 12 isotope is the most abundant isotope of carbon and has been chosen as the standard.

• Bh-a short-lived radioactive chemical element that does not occur in nature and is produced by bombarding bismuth with chromium nuclei

• Bohrium is a synthetic element, produced by the cold fusion of bismuth-209 and chromium-54.  
• The longest-lived isotope, bohrium-262, has a half-life of 0.1 seconds.  As is the case with several of the transfermium elements on the periodic table, there was some controversy over the initial discovery of element 107
