Where is gold on the periodic chart?
Group 11
gold (Au), chemical element, a dense lustrous yellow precious metal of Group 11 (Ib), Period 6, of the periodic table of the elements. Gold has several qualities that have made it exceptionally valuable throughout history.
What elements make up of gold?
Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable).
What are the three elements of gold?
The first 3 elements to be formed in the universe after the big bang are speculated to be hydrogen, helium, and lithium. It can be noted that the majority of the universe featured only hydrogen and helium shortly after the big bang, and only trace amounts of lithium existed. Was this answer helpful?

- Gold is prized for its beauty.
- Gold is malleable, so it can be flattened into extremely thin sheets.
What type of metal is gold?
transition metal
Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, veins, and alluvial deposits.
What are the 3 elements of life?
Many elements make up the human body, but only three occur in abundance. These elements, oxygen, carbon, and hydrogen, combine to form the constituents of some of the most essential processes in the human body, such as cellular respiration.
