Mendelevium (101Md) adalah sebuah unsur buatan, sehingga berat atom standarnya tidak dapat diberikan. Seperti semua unsur buatan, ia tidak memiliki satu pun isotop stabil. Isotop pertama yang disintesis adalah 256Md (yang juga merupakan isotop pertama dari setiap unsur yang menghasilkan satu atom pada satu waktu) pada tahun 1955. Ada 17 radioisotop yang diketahui, mulai dari 244Md hingga 260Md, dan 5 isomer nuklir. Isotop yang berumur paling panjang adalah 258Md dengan waktu paruh 51,3 hari, dan isomer yang berumur paling panjang adalah 258mMd dengan waktu paruh 57 menit.
