Thekey difference在锌和氧化锌之间是锌是一种化学物质elementwhereas zinc oxide is a chemical化合物.
锌是一种金属化学元素D块of the periodic table of elements. It forms many compounds such as oxides, sulfides, etc. Zinc oxide is one such chemical compound that contains zinc and oxygen atoms. It exists as a white solid. Let us talk more details on zinc and its oxide below.

什么是锌?
Zinc is a chemical element having the atomic number 30 and the chemical symbol Zn. This chemical element resembles magnesium when we consider its chemical properties. This is mainly because both these elements show +2 oxidation state as the stable oxidation state and also the Mg+2和Zn+2阳离子的大小相似。而且,这是24thmost abundant chemical element on the earth’s crust. Some chemical facts about zinc are as follows:
- 化学符号 - Zn
- 原子数 - 30
- Standard atomic weight – 65.38
- Appearance – silver grey solid
- Group – 12
- Period – 4
- Block – d block
- Element category – post-transition metal
- Electron configuration – [Ar] 3d104s2
- 标准温度和压力 - 固相处的相位
- Melting point – 419.53 °C
- 沸点 - 907°C
- Crystal structure – hcp (hexagonal close-packed)
When considering the zinc metal, it is adiamagneticmetal and has a bluish-white lustrous appearance. At most temperatures, this metal is hard and brittle. However, it becomes malleable in between 100 and 150 °C. Moreover, this is a fair conductor of electricity. However, it has low melting and boiling points when compared to most other metals.
When considering the occurrence of this metal, the earth’s crust has about 0.0075% of zinc. We Cn find this element in soil, sea water, copper and lead ores, etc. Moreover, this element is most likely to be found in combination with sulfur.
什么是氧化锌?
Zinc oxide is a chemical compound having the chemical formula ZnO. It is an inorganic compound. The oxidation state of zinc in this compound is +2 and for oxygen, it is -2. It appears as a white solid that is insoluble in water. However, in nature, it occurs as the mineral Zincite; a rare mineral. This mineral contains manganese and some other impurities. Therefore, it appears as a yellow or red colour. Apart from that, crystalline zinc oxide is thermochromic. It means that its white colour converts into a yellow colour upon heating in air and it can turn back to white colour upon cooling. Some chemical facts about zinc oxide are as follows:
- Chemical formula – ZnO
- Molar mass – 81.38 g/mol
- 外观 - 白色固体
- 标准温度和压力 - 固相处的相位
- 熔点 - 1,975°C
- Boiling point – decomposes above 1,975 °C
- Crystal structure – Wurtzite
我们将这种化合物用于橡胶,塑料,陶瓷,玻璃,水泥,润滑剂等的生产中。此外,它具有半导体特性。为了用作半导体,该化合物具有的有利特性是透明度,高电子迁移率,宽带盖,等等。
What is the Difference Between Zinc and Zinc Oxide?
Zinc is a chemical element having the atomic number 30 and the chemical symbol Zn whereas the zinc oxide is a chemical compound having the chemical formula ZnO. This is the key difference between zinc and zinc oxide. That is, the zinc oxide is an inorganic compound derived from zinc chemical element. It is in combination with oxygen. Since zinc is a chemical element, we can give its atomic weight (the standard atomic weight is 65.38 for zinc) while we can give the molar mass or molar weight for zinc oxide (molar mass is 81.38 g/mol.) because it is a chemical compound.
此外,外观中锌和氧化锌之间也存在差异。锌作为有光泽的银灰色固体出现,而氧化锌在标准温度和压力下显示为白色固体。除此之外,锌和氧化锌之间的另一个区别是,我们可以在半导体的制备中使用氧化锌,但仅锌没有半导体特性。

摘要 - 锌与氧化锌
Zinc is a chemical element that we know very well as a metal. Zinc oxide is an inorganic compound which contains zinc and oxygen in combination with each other. Thus, the key difference between zinc and zinc oxide is that zinc is a chemical element whereas zinc oxide is a chemical compound.
