What is the total number of electrons in a Cu+ ion?
(1) 28 (3) 30(2) 29 (4) 36

Answers

Answer 1

Answer:

Answer: The number of electrons in Cu^+ ion is 28.

Explanation: Copper has atomic number of 29 which means it has 29 electrons and 29 protons.

Argon is the noble gas with 18 electrons.

$Cu(29 -[Ar]3d^(10)4s^1$

When Cu lose one electron it forms $Cu^+$ as now the number of protons are greater than the number of electrons.

The configuration of $Cu^+$ becomes $[Ar]3d^(10)$

Answer 2

Answer:

The total number of electrons in a Cu+ ion is 28.

The Cu+ ion is an ion of copper with a +1 charge. The charge of the ion tells us the number of electrons gained or lost by the atom. Since the ion has a positive charge, it means that it has lost one electron.

The atomic number of copper (Cu) is 29, meaning that a neutral copper atom has 29 electrons. When a copper atom loses one electron to form the Cu+ ion, the total number of electrons in the ion is 29 - 1 = 28.

The valency of chlorine is one.why?

Answers

Answer:

Explanation:

The electronic configuration of chlorine can be written as 2, 8, 7. ... Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.

If the formic acid were replaced with a strong acid such as HCI at the same concentration (2.0 M). how would that change the volume needed to reach the equivalence point? (A) The change would reduce the amount, as the acid now fully dissociates. (B) The change would reduce the amount, because the base will be more strongly attracted to the acid. (C) The change would increase the amount, because the reaction will now go to completion instead of equilibrium. (D) Changing the strength of the acid will not change the volume needed to reach equivalence.
