The mass of a proton is approximately 1836 times greater than that of an electron if the mass of a neutron is the same as that of a proton approximately how many atoms are in a 1-kg mass of copper?

Most of the information in the question is not needed in order to answer it; this is the sort of thing that some teachers do to trap their students. tut tut!
You need to know the Atomic Mass of copper, which is ~ 63.55. This tells you that the gram-atomic-mass (GAM) of copper is 63.55 grams. You have 1000gm of copper (and that is the only info you need from the question.)
1000/63.55 ~=15.7. So, you now know that you have 15.7 GAMs of copper.
The last thing you need is something called Avogadro's number. Named after the chemist who first measured it, this is the number of atoms in one GAM. The number is ~6 x 1023 . Therefore 15.7 x 6 x 1023 ~= 9.4 x 1024 atoms.

What is the full electron configuration of copper plus 2 ion?
The electron configuration of copper(II) is [Ar] 3d9 . Copper is [Ar] 3d10 4s1
What is the outer electron configuration for copper?
The electron configuration of copper is 1s22s22p63s23p63d104s1.
Why iron is not a good conductor of heat if it compair to copper?
Copper has relatively easily available electron as compare to the iron because copper has bigger atomic size than iron which means the shielding effect in copper is more than iron so the electron of copper can conduct heat more easily and efficiently as compare to the electron of the iron which make iron not a good conductor of heat if it is compair to copper.
Why does copper have one valence electron?
One electron is "borrowed" from the 4s shell to completely fill up the 3d shell. This is as the nearness of the energy between the two shells results in blurring of the order of electron selection. The same thing happens in chromium.
What is the mass number of the atom if the protons and electrons are both 29 and the neutron is 35?
This isotope is copper-64.
What is the full electron configuration of copper plus 2 ion?
The electron configuration of copper(II) is [Ar] 3d9 . Copper is [Ar] 3d10 4s1
How many orbits does copper have?
Copper has four electron shells.
Is copper the best conductor?
because copper atom has one electron in outer shell and easy to to energize to flow to other copper atom we now that the rate of flow of electron is current
What is the correct electron configuration for Cu?
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
What is the outer electron configuration for copper?
The electron configuration of copper is 1s22s22p63s23p63d104s1.
Why iron is not a good conductor of heat if it compair to copper?
Copper has relatively easily available electron as compare to the iron because copper has bigger atomic size than iron which means the shielding effect in copper is more than iron so the electron of copper can conduct heat more easily and efficiently as compare to the electron of the iron which make iron not a good conductor of heat if it is compair to copper.
What is the electron configuration of copper 1 ion?
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
What has greater mass 1 L copper or 1 L silver?
copper
How many valence electrons does conductors such as copper have?
only one valance electron does a conductor such as copper have.
Is D block element copper?
The outermost electron of copper is situated in d block. Therefor copper is a d block element.
Where did copper form?
Copper can only form in supernova explosions, when a dead star collapses to become either a neutron star or a black hole.
Abbreviated electron configuration for copper?
The abbrieviated electron configuration of copper is [Ar] 4s23d9
