What family is gold in?
transitional metal family
Gold is a noble metal and falls into the transitional metal family on the periodic table in group number 11. The actual discoverer of gold is unknown as the metal has been in use by humans for over 5,000 years. Gold is extremely dense, weighing in at 19.3 grams per cubic centimeter.

What family does bromine belong to?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What element is similar to gold?
Transition metalToxic heavy metalPeriod 6 elementGroup 11 element
As a metal, gold exists as lot of atoms in a sea of electrons and it is thus like many other metals (most of the Periodic Table). In the Periodic Table it is in Group 11 and has atomic number 79. In the same group above it is silver (Gp 11), and adjacent to it are platinum (Gp 10,AN 78) and mercury (Gp 12, AN 80).
What is gold made from in elements?
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).
Is gold an element compound or mixture?
Gold, for example, is element number 79. Gold bars, gold nuggets, gold dust, coins, and jewelry are all made of the same type of atoms, and they cannot be broken down into anything simpler. The atoms in one piece of gold are identical to the atoms in any other. Therefore, gold is considered an element.
What is a family of elements?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered. Groups may also be identified using their topmost element, or have a specific name.
Is bromine a compound or mixture?
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
What elements does gold have?
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal….Gold.
Which metal is closest to gold?
What Is Brass? Brass is not a pure metal like gold – it is an alloy of 67% copper and 33% zinc (the percentages may vary). It looks similar to gold and has a similar yellowish color, and it is sometimes used in decorations and jewelry.
How did the bromine element get its name?
The name comes from the Greek ‘bromos’ meaning stench. A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell.
What is the atomic number of bromine at room temperature?
Bromine is a chemical element with symbol Br and atomic number 35. Classified as a halogen, Bromine is a liquid at room temperature. H.
Which is the best form of gold bromide?
Gold Bromide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered.
Where can you find bromine in the world?
Today, bromine is primarily obtained by treating brines from wells in Michigan and Arkansas with chlorine. From the Greek word bromos, stench. Discovered by Balard in 1826, but not prepared in quantity until 1860. Bromine is the only nonmetallic liquid element.
