Of protons in an atom of the element=atomic no.=29. Of neutrons in an atom of the element=mass no.-atomic no.=64-29=35. Of electrons in a neutral atom of the element=atomic no.=29. Electronic configuration of the element is 1s2 2s2 2p6 3s2 3p6 3d10 4s1. Thus, 4 shells hold the electrons of the each atom in the element Copper.
- 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?
- Copper is a reddish orange metal that has the atomic number 29 in the periodic table. It is a Transition metal and located in Group 11 of the periodic table. It has the symbol Cu. Copper (Cu) is a soft and malleable metal that has a high thermal and electrical conductivity.
Explanation is in a file
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!
Atomic mass is nuetrons + protons.
? 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'
The answer is B. It has a central nucleus composed of 29 protons and 35 neutrons, surrounded by an electron cloud containing 29 electrons.
