It takes 60 days for 1024 grams of element xy to decay to 32 grams. what is the half life of element xy

The half life of element XY is 12 days

Explanation:

Given:

Time taken for  1024 grams to decay into 32 grams  = 60 days

To Find:

The half life of element XY = ?

Solution:

The Half life is calculated by

=

Substituting the values,

=

=

=

= 12

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.
