Because it has 29 protons in its nucleus. The atomic number is the number of protons in an elements nucleus.
The number of protons is the atomic number.
The atomic number of an atom is determined by the number of protons it has.
The number of protons in an atom is equal to its atomic number.
Z, or the atomic number, represents the number of protons in a element as opposed to A, which is the mass number, the number of protons and neutrons.
Protons are subatomic particles that determine the atomic number of an element. The number of protons in an atom's nucleus is what defines its atomic number; this uniquely identifies each element on the periodic table.
The atomic number of copper is 29, which means that a copper atom has 29 protons in its nucleus.
A copper atom has 29 protons in its nucleus. The number of protons of an atom is equal to the atomic number of the element in the periodic table.Copper's atomic number is 29, so a copper atom contains 29 protons.Atomic number = number of protons.It contains 29 electrons,29 protons and 34 neutrons.As copper is element number 29, it has 29 protons. The proton number is the same as the element number shown in the periodic table.
Thee same as the atomic number of copper: 29.
A copper atom contains 29 protons and 29 electrons. The number of protons in an atom determines its atomic number, which for copper is 29. As atoms are electrically neutral, the number of protons must equal the number of electrons.
Yes, an atom of copper contains electrons. copper is a neutral atom, thus the number of protons will equal the number of electrons. coppers atomic number is 29, thus there are 29 electrons and 29 protons in a copper atom.
The atomic number of an atom is equivalent to the number of protons in its nucleus.
The number of protons is the atomic number.
The atomic number of an atom is determined by the number of protons it has.
The atomic number is determined by the number of protons in an atom. Therefore, if an atom has 65 protons, its atomic number is 65.
The number of protons in an atom is its atomic number.
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
The number of protons in an atom is equal to its atomic number.
