Ini adalah tabel periodik<\/a> di mana elektron valensi diberi label.<\/p>\n

Mari kita pahami konsep elektron valensi<\/a> beserta jumlah elektron valensi unsur golongan utama dan unsur transisi<\/a> .<\/p>\n

Apa itu elektron valensi?<\/strong><\/h2>\n

Elektron valensi adalah elektron yang terletak di kulit terluar atau tingkat energi<\/a> suatu atom<\/a> yang terlibat dalam ikatan kimia.<\/p>\n

Misalnya magnesium<\/a> mempunyai 2 elektron pada orbit<\/a> terluarnya, sehingga mempunyai 2 elektron valensi. [1]<\/sup><\/a> <\/p>\n

\"elektron<\/figure>\n

Elektron ini bertanggung jawab atas sifat kimia suatu unsur, seperti reaktivitasnya dan jenis ikatan kimia yang dapat dibentuknya dengan atom lain.<\/p>\n

Jumlah elektron valensi suatu atom menentukan posisinya dalam tabel periodik dan kemampuannya membentuk ikatan kimia<\/a> .<\/p>\n

Elektron valensi unsur golongan utama<\/strong><\/h2>\n

Unsur golongan utama, disebut juga unsur perwakilan, terletak pada golongan 1, 2, dan 13 hingga 18 pada tabel periodik.<\/p>\n

Jumlah elektron valensi unsur-unsur tersebut sama dengan nomor golongannya.<\/p>\n

Misalnya, unsur Golongan 1, seperti litium<\/a> dan natrium<\/a> , memiliki satu elektron valensi, sedangkan unsur Golongan 2, seperti magnesium<\/a> dan kalsium<\/a> , memiliki dua elektron valensi.<\/p>\n

Unsur golongan 13, seperti boron<\/a> dan aluminium<\/a> , memiliki tiga elektron valensi, dan seterusnya.<\/p>\n

Elektron valensi ini bertanggung jawab atas sifat kimia unik dan reaktivitas unsur.<\/p>\n

Elektron valensi unsur transisi dan unsur transisi internal<\/strong><\/h2>\n

Elektron valensi unsur transisi<\/a> dan unsur transisi internal<\/a> lebih rumit untuk ditentukan dibandingkan dengan unsur golongan utama.<\/p>\n

Memang benar, sublapisan<\/a> d dari elemen transisi dan sublapisan f dari elemen transisi internal tidak terisi lengkap dan sangat dekat dengan sublapisan luar s.<\/p>\n

Akibatnya, elektron subkulit d dan s pada unsur transisi serta subkulit f dan s pada unsur transisi internal dapat berperilaku seperti elektron valensi.<\/p>\n

Untuk unsur transisi, elektron valensi dapat berkisar antara 3 hingga 12 karena kontribusi elektron subkulit d dan subkulit s. Dalam beberapa kasus, elektron pada orbital d yang tidak lengkap juga dianggap sebagai elektron valensi. [2]<\/p>\n

Demikian pula, untuk unsur transisi internal (atau unsur blok f), elektron valensi dapat berkisar antara 3 hingga 16 karena kontribusi elektron subkulit f dan subkulit s. [3] Elektron pada orbital d yang tidak lengkap juga dapat dianggap sebagai elektron valensi pada beberapa logam transisi internal.<\/p>\n

Penting untuk diperhatikan bahwa untuk unsur transisi dan transisi internal, elektron valensi adalah elektron yang terdapat pada kulit di luar inti gas mulia.<\/p>\n","protected":false},"excerpt":{"rendered":"
