亜鉛は青みがかった白色で光沢のある[[diamagnetic/ja|反磁性]]金属であるが、一般的な市販グレードの多くはくすんだ仕上げが施されている。密度は[[iron/ja|鉄]]よりもやや低く、六角形の[[crystal structure/ja|結晶構造]]を持ち、歪んだ形の[[Close-packing of equal spheres/ja|六角クローズパッキング]]を持つ。この金属はほとんどの温度で硬く脆いが、100～150 °Cの間では可鍛性になる。210 °Cを超えると再び脆くなり、叩いて粉砕することができる。亜鉛はかなりの[[electrical conductivity/ja|電気伝導体]]である。金属としては融点（419.5 °C）と沸点（907 °C）が比較的低い。融点は[[mercury (element)/ja|水銀]]と[[cadmium/ja|カドミウム]]を除けば[[d-block/ja|d-ブロック]]金属の中で最も低く、このため亜鉛、カドミウム、水銀は他のd-ブロック金属と同様に[[transition metal/ja|遷移金属]]とは見なされないことが多い。

~~Zinc is a bluish-white, lustrous,~~ [[diamagnetic]] ~~metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than~~ [[iron]] ~~and has a hexagonal~~ [[crystal structure]]~~, with a distorted form of~~ [[Close-packing of equal spheres|~~hexagonal close packing~~]], in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 ~~°C. Above 210~~ ~~°C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair~~ [[electrical conductivity|~~conductor of electricity~~]]~~. For a metal, zinc has relatively low melting (419~~.5 ~~°C) and boiling point (907~~ ~~°C). The melting point is the lowest of all the [[d-block]] metals aside from~~ [[mercury (element)|~~mercury~~]] ~~and~~ [[cadmium]]~~; for this reason among others, zinc, cadmium, and mercury are often not considered to be~~ [[transition metal]]~~s like the rest of the d-block metals.~~
