- The mass number (A) of sodium is given as 23. Step 2: Determine the Number of Protons- The number of protons in an atom is equal to its atomic number.- Therefore, the number of protons in sodium = Atomic Number = 11. Step 3: Determine the Number of Electrons- In a neutral ...
The number of protons in an anion must always be ___ the number of electrons. A monatomic ion with a charge of -1 has an electronic configuration of 1s^22s^22p^63s^23p^64s^23d^{10}4p^6 . 1. This ion is a(n) an...
A number of electrons having l+m value equal to zero in 26Fe may be: (A) 13 (B) 14 (C) 7 (D) 12 What will be the charge on 500 mg of electrons? Write the electron configuration for the Br- ion, which has 36 electrons. ...
number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons.
Only a neutral atom possesses an equal number of protons and electrons, the atomic number of an element is equal to the number of electrons in the neutral atom, not in the ion. An ion, on the other hand, is generated by removing electrons from a regular atom or adding electrons to a ...
- the loss of electrons by metals Example: Sodium (Na) loses one electron (e ─ ) and becomes a positive (+1) ion Oxidation number Na O → Na +1 + e ─ - Sodium is oxidized and is a reducing agent (something else gains the electron lost by sodium) ...

He modified the Niels Bohr atomic theory by considering the elliptical path of electrons. Similarly, he also modified the special relativity theory by formulating the Sommerfeld model for energy in which the energetic levels are distributed into numerous parts. He was the first to come up with an...
Current flows through the electrodes via the movement of electrons. An electrolyte is a phase in which charge is carried by ions. For example, a solution of table salt (sodium chloride, NaCl) in water is an electrolyte containing sodium cations (Na + ) and chloride anions (Cl − ). ...
