What is a cation and where can you find it in the periodic table? ?

pls

Cations are positively charged ions, due to loss of electrons in an atom

Explanation: Cations are usually metals and are found primarily on group 1 alkali metals, group 2 alkali earth metals, group 3 Boron group and transition metals.

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.
