Me with these questions i don't get science how many different elements are in our bodies? what are the 6 elements that make up 95% of our bodies?

There are at least 60 elements in our bodies.

Other elements may be present, but in such small quantities that we cannot detect them with current technologies.

The six most abundant elements (by mass) in our bodies are:

Oxygen           65    %

Carbon            18    %

Hydrogen       10    %

Nitrogen          3.2 %

Calcium           1.4 %

Phosphorus    1.1  %

TOTAL =      99     %

a electronegativity decreases beacuse the size of nucleus is bigger.
