With the middling atomic number 30, it has five stable isotopes of atomic weight from the dominant zinc 64 to zinc 70, plus an extra 25 radioisotopes.
- Zinc has the element symbol Zn and atomic number 30, making it a transition metal and the first.
- Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table.It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110°C and 150°C.
About Zinc
Zinc is a softish metal of light grey color and is one of so called transition metals. Its name comes from a similar German word which is believed to be a copy of an old Persian word meaning stone. It is impossible to find pure zinc on our planet, but it can be extracted from a number of minerals and compounds. Zinc is essential for normal chemical processes in living organisms, and in micro-doses it exists in our enzymes. Large or even medium dozes of zinc can be toxic. This metal is widely used as a galvanizer, in such products as lamp posts, some parts of automobiles, etc. As a part of an alloy with copper called brass, zinc is used for producing parts of musical instruments, and zinc is also used to produce many other alloys. Oxides of this chemical element are used for producing rubber, plastic, textiles, soaps, cosmetics, electrical components, and many other goods.

Explanation:
The atomic number of zinc is 30, which means that all zinc atoms have 30 protons in their nuclei. A neutral atom has equal numbers of protons and electrons, so a neutral atom of zinc would have 30 electrons.
The electron configuration of a neutral zinc atom is

Zinc is a d-block element, also known as a transition element. For the d-block elements, the outermost s-sublevel has higher energy than the d-sublevel, which is contrary to what the Aufbau diagram indicates.
When d-block elements lose electrons, they lose the highest energy s electrons first, which in the case of zinc are the two 4s electrons. Having eight 3d electrons and two 4s electrons is much less energetically stable than ten 3d electrons and no 4s electrons.
