Silver - Wikipedia

2019-5-6 · Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table, copper and gold.Its 47 electrons are arranged in the configuration [Kr]4d 10 5s 1, similarly to copper ([Ar]3d 10 4s 1) and gold ([Xe]4f 14 5d 10 6s 1); group 11 is one of the few groups in the d-block which has a completely consistent set of electron configurations.

Boron nitride - IPFS

Boron nitride is a heat- and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.
