Question

ACTIVITY 1.1. WRITE THE NUCLEAR REACTION INVOLVED IN THE SYNTHESIS OF EACH OF THE FOLLOWING NEW ELEMENTS.

A.Curium(Z=96) was formed by reacting Pu-239 with alpha particles ⁴²He,it has a half -life of 162 days.

B.Mendelevium(Z=101) was formed by reacting En-253 with alpha particles.

C.Meitnerium(Z=109) was formed by cold fusion which involves the combination on Bi and Fe nuclides at ordinary temperature.

Answer 1

A.

$_{94}^{239}Pu+_2^4He\to_{96}^{242}Cm+_0^1n,$

B.

$_{99}^{253}Es+_2^4He\to_{101}^{256}Md+_0^1n,$

C.

$_{83}^{209}Bi+_{26}^{58}Fe\to_{109}^{266}Mt+_0^1n.$
