Short Answer:
The 4 atoms, O, C, H and N are about 96% of our mass, but with calcium added in the group of 5 represents more than 97% of the body mass of the average person.
Accounting by Mass:
The mass of the human body is provided mostly by oxygen, carbon, hydrogen, nitrogen. Together these elements account for about 96% of the mass of a human.
Add in about a kilogram of calcium in the bones and body fluids and you are up to 97.4%. All of this depends on the particular person since water, our major component, can differ by 10% from one individual to another.
That said, typically the breakdown goes like this.
Oxygen: 65% of the mass
Carbon: 18% of the mass
Hydrogen: 10% of the mass
Nitrogen: 3% of the mass
Calcium: 1.4 % of the mass
Phosphorus 1.1% of the mass
With phosphorus, one has accounted for 98.5% of the mass of the typical human and that will change by a couple of tenths from person to person.
Accounting by Numbers:
Numerically we have nearly twice as many hydrogen atoms in our bodies as compared to all other elements combined. Specifically, hydrogen counts as 63% of our atoms by number, give or take a bit, but being so light it barely gets to 10% of our mass. Oxygen atoms count as 24% and carbon atoms are a mere 12% of the populations. Together, our three basic organic building blocks account for 99% of all the atoms in the body.
Caveat:
As was said above, the water content of the human body weight varieties between 55 to 65 % from one person to the next and being the major component changes the numbers above a little for each individual.
Summary:
Almost 99% of the mass of the human body is made up of the six elements oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Most of the last 1% is made up of five elements: potassium, sulfur, sodium, chlorine, and magnesium, but a tenth of a percent or so is made up of another dozen or so elements which include those recognized as essential to health such as iron, iodine and fluorine as well as beneficial trace elements like manganese, copper and zinc.
Gold is not one of the six elements that make up most of the human body. The six main elements are oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

The five main elements found in nucleic acids are carbon, hydrogen, oxygen, nitrogen, and phosphorus. These elements make up the building blocks of DNA and RNA molecules, which are essential for storing and transmitting genetic information in living organisms.
Some vital organs in the human body include:BrainHeartLungsKidneyLiverSkinIntestinesPancreasStomach
The human body consist of many different elements, but the three main elements are:Oxygen (65%)Carbon (18%)Hydrogen (10%)

The five main uses of energy in the human body are for metabolism, physical activity, maintaining body temperature, growth and development, and cellular processes.

The four elements that make up the greatest percentage of the human body by percentage of body mass are oxygen (65%), carbon (18.5%), hydrogen (9.5%), and nitrogen (3.2%) but there are many others in smaller amounts.
