Is it possible to collect all the elements?
Is it possible to collect all the elements?
Collecting elements presents its own unique challenges. For one, collecting them all is actually impossible! Some are toxic, radioactive, or won’t stick around long because they have short half-lives (they decay into more stable elements).
Where can I find pure elements?
Here are some examples of pure elements that might be found in a home:
- Argon and tungsten are in incandescent light bulbs.
- Mercury is in some thermostats and in switches in space heaters that turn off when tipped over.
- Copper is used in electrical wiring and in some water pipes.
- Carbon is in pencils.

How can I memorize Valency easily?
The easiest method of determining valences is to just look at the periodic table. Place a copy of the periodic table elements on a surface where all of the atoms represented on the table are easily reached.
Is the Valency of oxygen?
Oxygen has 8 valence electrons. Hence it has a valency of 6.
What is the Valency of gold?
Gold is a metallic element and a transition element having a formula Au. It has the valency of 3 or 1.
Why is silver a valence of 1 and 2?
Answer. This property is called as variable valency. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency.
What is silver Valency?
The valency of the element represents the number of bonds that an atom can form as part of a compound. The most common valency of silver metal is 1 and 3.
