Answer:
The atom becomes positively charged.
Explanation:
- An ionic compound is defined as the compound formed by transfer of electrons from one atom to another.
For example, lithium atom on donating its one valence electron to chlorine atom will result in the formation of an ionic bond and the compound formed is LiCl.
- A molecule is defined as a substance which can contain either same or different elements.
For example,
,
etc are molecules.
- A molecule can contain either a covalent or ionic bond. But an ionic compound will always contain an ionic bond.
The atomic number of Cu = 29
Valence electron configuration of Cu = 3d¹⁰4s¹
Cu+ is formed when 1 electron is lost from Cu. Therefore, the atomic number for Cu+ = 28
Similarly, loss of 2 electrons from Cu results in Cu2+ with an atomic number = 27
Cu+ is the larger ion. This is because as electrons are removed from the valence orbitals, the attraction between the outer electrons and the nucleus tends to increase which then results in a decrease in size.
Ans: Cu+ has one more electron
Answer:
1s2 2s2 2p6 3s2 3p6 4s2
shorthand: [Ar] 4s2
Explanation:
the end number values are exponents, so 1s^2
