Elements are identified by number of protons on the periodic table. Number 15 is Phosphorus.
The number of protons in an atom's nucleus determines its chemical identity.
If phosphorus is neutral-charge, there are 15 of each.
The number of protons in the nucleus of the atom determine its identity.
What is unique to each atom and provides the elemental identity of an atom is the number of protons in the nucleus. Only that.
Any atom should have equal number of protons and electrons. If the atom contains 15 protons then it must contain 15 electrons.
The number of protons in an atom's nucleus determines its chemical identity.
The atom identity is given by the number of protons.
If phosphorus is neutral-charge, there are 15 of each.
The number of protons establishes the elemental identity of an atom.
the one thing that gives an atom its identity is the mass number and the atomic number
The number of protons in the nucleus of the atom determine its identity.
All phosphorus atoms have 15 protons (hence their atomic number of fifteen). Assuming the atom is neutral, it will also have an equal amount of electrons.
An atom's identity is determined by the number of protons in its nucleus, which is called its atomic number. This number determines the element to which the atom belongs. Electrons can be gained or lost to form ions, but as long as the number of protons remains the same, the atom's identity remains unchanged.
What is unique to each atom and provides the elemental identity of an atom is the number of protons in the nucleus. Only that.
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
An atom with 15 protons, 15 neutrons, and 15 electrons.
Any atom should have equal number of protons and electrons. If the atom contains 15 protons then it must contain 15 electrons.
