What is the charge of a molecule having 14 electrons and 12 protons? What subatomic particle has a neutral charge? What charge would an ion that has 11 protons, 11 neutrons, and 10 electrons would have? What charge does hydrogen have?
An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your...
An atom is identified by the number of protons present in its nucleus which is called its atomic number. The mass number describes the total number of protons and neutrons. Using the number of protons, electrons and neutrons, we can identify and label the atomic or ionic species....

The ancients believed that everything is made of just five elements – earth, water, fire, air and aether. Five is much simpler than 118. It's also wrong. By 1932, scientists knew that all those atoms are made of just three particles – neutrons, protons and electrons. The neutrons and...
The atomic number of yttrium is39. . An isotope with an atomic mass of 193 has 116 neutrons. What does Z mean in Chem? Z =atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus; A = mass number = number of protons and neutrons in the most commo...
Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a negligible effect. Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a ...
