Atomic Number 29

Dictionary entry details

Origin of Name: From the Latin word cuprium, referring to the island of Cyprus: Date of Discovery: Known to the ancients: Discovered by: Copper beads dating back to 9000 B.C. Were found in Iraq.

Atomic number of Cu = 29 The electronic configuration of Cu is, The reason for abnormal electronic configuration of Cu is because of the half-filled and fully-filled configuration are the more stable configuration. In this configuration, the d-subshell is fully-filled and s-subshell is half-filled which makes the Cu more stable. These subshells are made up of atomic orbitals. The four subshell labels that are used are s, p, d, and f. The maximum number of electrons allowed in each of these subshells are 2, 6, 10, and 14 respectively. For example, the names of the subshells in a sulfur atom would be 1s, 2s, 2p, 3s, and 3p (since sulfur has three electron shells). Would the phrase 'different mass number, same atomic number' be correct in describing an isotopes? 27 If a neutral copper atom (atomic number 29) becomes an ion that has a charge of 2+, how many electrons does the resulting ion have?

Explanation:

Answer is B.

B. It has a central nucleus composed of 29 protons and 35 neutrons,surrounded by an electron cloud containing 29 electrons.

I hope it's helpful!

Explanation:

Atomic mass is nuetrons + protons.

Basically it's

? nuetrons + protons = 64

I did process of elimination:

b) It cannot be 'b' because 29 + 64 doesn't equal 64.

c) It cannot be 'c' because in a regular molecule the amount of protons equals to amount of electron(s).

d) 29 + 29 doesn't = 64.

Therefore, the answer is 'A'

it's B
