Currently, no element has ever been given a chemical symbol 'Z.'
Although, you may wish to consider these facts.
Atomic NumberEvery element included on the Periodic Table does have a property known as its atomic number conventionally represented by the letter 'Z.' The atomic number 'Z' is simply a variable used to encapsulate the number of protons within a given atom's nucleus.
Ex. Helium
In the unlikely event that chemists everywhere were to agree upon making a 'small' tweak to the standard notation by dropping just one of the many lower-case letters among the two-lettered chemical symbols, the substance most likely to fit your criteria would be either Zinc (Zn, Z = 30) or Zirconium (Zr, Z = 40). The logic is simple. They both begin with the Latin letter 'z.'
Of course, we change element names around as rarely as possible. The reason is to avoid confusion with the other Z's. We could change the symbol of either Zinc or Zirconium to Zwould make writing down one of these elements about 50% quicker. However, we would still be causing confusion for no goodreason. Note that sometimes causing confusion is necessary in scientific nomenclature.
Following the eventful year of 2006, astronomers agreed there were finally enough 'good' reasons to change the definition of a planet. Actually, they restricted the guidelines for a celestial body to fit the definition of a planet. Confusion (not to mention resistance and anger) resulted since Pluto was to be excluded from the group of planets. Today our Solar System has exactly eight planets instead of nine and is debated to this day. However, the symbol for Yttrium (once Yt) seemed to quietly slip away in the 1920's, giving precedence to its shorter version, (now official) the chemical symbol Y. This occurred even though Ytterbium (Yb) could have easily taken the shorter version as well. Go figure.
Particle PhysicsThe periodic table is in no way a complete representation of the simplest forms of matter in the universe. In fact, an atom is quite complex compared to what we call 'elementary particles.'
For example, a common isotope of a Lithium atom has three protons, and four neutrons at its core. These seven nucleons (not elementary) are held together by other bits of matter, interacting within the nucleus. One type of these bits is the Z particleand it has a mass greater than an entire Iron atom (Fe). That last part probably won't make sense until you've passed college-level quantum mechanics, at least.
The Z particle (or Z boson) isn't on the periodic table of elements, but it is on the chart of fundamental particle and interactions.
The element 'H' is hydrogen, and is NO. 1 in the Periodic Table.
There is NO element in the Periodic Table with the symbol 'Hn'. The nearest is hydrogen (H).
Element 56 on the periodic table is Barium (Ba).
84th element is polonium (Po). It is in the same Group as Oxygen.
The only element which has the symbol Au is gold.
There are two on the Periodic Table of Elements, both transition metals: Zinc, number 30 and Zirconium, number 40.
The element abbreviated with As on the periodic table is Arsenic
No, carbon is not the first element on the periodic table of elements. Hydrogen is the first element on the periodic table.
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
The common ion charge of an element, Z, can be determined by looking at its position on the periodic table and its group number. Elements in the same group tend to have the same common ion charge due to their similar electron configurations. You can also refer to a periodic table to determine the common ion charge of element Z.
A group in Periodic Table is the column of element in periodic table
No, hydrogen is ?the lightest element in the periodic table.
Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
The element 'H' is hydrogen, and is NO. 1 in the Periodic Table.
There is NO element in the Periodic Table with the symbol 'Hn'. The nearest is hydrogen (H).
The element potassium is represented by the abbreviation K in the periodic table.
Element 56 on the periodic table is Barium (Ba).
