The group number of Au is 11. Its period number is 6.
group 18, all periods
Gold (AU) is an alkaline earth metal with a relative Atomic Mass of 196.97, an atomic number of 79 in group class 1B
Same periods as the ones next to them (ie. 4-7). Called 'transition metals', has no group number.
The vertical "groups" group elements by chemical properties the horizontal "periods" group elements by the number of energy levels
The period number is equal to the number of shells. Periods are the horizontal rows on the periodic table. The number of shells increases down a group.
cu,ag, and au are all in what group
A period is a group of 3 digits in a number. For example: 6,756,215,985,000,000 .this number has 5 periods, because every group of 3 digits counts as a period. Another example: 214,587,425. this number has 3 periods. another example: 12. this number has 0 periods. another example: 54,554,215,487,256,542,154,252,563,253,256,896,585,487,545,468. (this number has 15 periods.) well...I hope I helped! :)

On the periodic table gold is Au and the atomic # is 79.
au numéro= means literally "at the number/at number"
Same periods as the ones next to them (ie. 4-7). Called 'transition metals', has no group number.
Elements in the periodic table are classified based on their properties and characteristics. They are organized by increasing atomic number and grouped into periods (rows) and groups (columns). Elements in the same group generally have similar chemical properties, while elements in the same period share the same number of electron energy levels.
The atomic symbol for gold is Au and its atomic number is 79.
An element's group is determined by its location on the periodic table. Elements within the same group share similar chemical properties and have the same number of valence electrons. The group number corresponds to the number of valence electrons an element has in its outermost energy level.
