Ra, would have the lowest ionization energy. Remember ionization energy increases going up and to the right.
Answer : The concentration of NaOH is, 0.336 M
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus, the concentration of NaOH is, 0.336 M
Answer:
gram
Explanation:
Gram is a SI unit (International Ststem of units)
other SI units : kg , meter, ampere, Kelvin
pound gallon and foot are SAE (or imperial) units
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
