A Periodic Table will be extremely helpful in this case. If you would've taken the smallest of glances, you could see that copper's (Cu) atomic number is 29.
A periodic table is in the link below should you decide to use it.
the element copper. 29 is its atomic number
Copper's atomic number is 29.
The chemical symbol for copper is "Cu" and its atomic number is 29.
The number of electrons is not the key factor in determining an element, because ions can have more or fewer electrons. However, assuming an element that hasn't gained or lost any electrons, the element would be Copper.
It depends entirely on the identity of the atom. Each element has a unique number of protons. In fact, the number of protons in an atom is what tells you what element it is! For instance, hydrogen (H) has 1 proton, carbon (C) has 6 and copper (Cu) has 29.If you look at the periodic table, than you'll see that each element in the table has a number. That number is called the atomic number, and that number is exactly equal to the number of protons in that particular element's nucleus.See the Web Links to the left of this answer for a periodic table
This is a single specific isotope of copper (element 29). The isotope 63Cu makes up about 70% of the copper on Earth, and most of the remaining 30% is the 65Cu isotope. The isotope 64Cu is also known, but this atom is not stable, having a half-life of just 12.7 hours.
29
Copper's atomic number is 29.
Copper has an atomic number of 29 on the periodic table of elements.
It is element 29 on the periodic table. The elements in the periodic table are arranged according to increasing atomic number. The atomic number is the number of protons in the element's atoms.
The chemical symbol for copper is "Cu" and its atomic number is 29.
The periodic table is an arrangement of elements and not compounds like CuCl. However copper chloride has two elements: copper (atomic number 29) and chlorine (atomic number 17).
The atomic number of copper is 29, therefore copper atoms contain 29 protons in their nuclei.
Atom number 29 on the periodic table is Copper. Its symbol is Cu. Its in the fourth period and the eleventh group/family.
Copper has 29th place in periodic table.It has atomic number of 29.It is a very ductile metal represented by symbol Cu.
Copper--Cu, atomic number 29--is in Group 11 Period 4.
The element with atomic number 29 is Copper (Cu). Copper is a transition metal in Group 11, Period 4 of the Periodic Table. It has 29 electrons in 4 shells with 1 electron in the outer shell.
The number of electrons is not the key factor in determining an element, because ions can have more or fewer electrons. However, assuming an element that hasn't gained or lost any electrons, the element would be Copper.
