Get the detailed answer: How many electrons does barium have to give up to achieve a noble-gas electron configuration. To achieve a noble-gas electron configuration, an atom of barium has to give up two electrons and become the positively charged ion represented as... See full answer below. B) Tellurium is a solid metalloid. Therefore, an element in a neutral state will have the same number of protons and electrons. A) 6 B) 1 C) 2 D) 7. c. When a barium atom becomes a barium ion, does the atom gain or lose electrons? Problem: How many electrons does barium have to give up to achieve a noble gas configuration? check_circle Expert Answer Step 1 The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. It has 2 atoms in its 5s shell and the remaining 36 are considered internal. Thus, to have a neutral charge, it must carry 56 electrons as well. C) Chlorine is a liquid non-metal. Protons and neutrons are in the center of the atom, making up the nucleus. D) Tellurium is a solid metalloid. Carbon is a chemical element with atomic number 6 which means there are 6 protons in its nucleus. How many valence electrons are in an atom of magnesium? Your dashboard and recommendations.
