The symbol of Bromine is Br and number of protons(or atomic number) which is also equal to the number of electrons is 35
Hg and 80 protons
Cu and 29 protons
The number of protons is the element's c) atomic number.
The number of an element on the periodic table is equal to the number of protons in a single atom of that element. Since mercury (symbol Hg) has the atomic number of 80, this means there are 80 protons in a single atom of mercury.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
Holmium: The number of protons per nucleus of an atom is the same as its atomic number.
The number equal to the total number of protons in the elementAtomic number:It is the following number in the Periodic Table, and by definition equal to the number of protons of the atom of that unique element.Example:Hydrogen, atom symbol H, number 1, protons: 1Carbon, atom symbol C, number 6, protons: 6Uranium, atom symbol U, number 92, protons: 92
O and 8 protons
Kr and 36 protons
Cu and 29 protons
The number of protons is different.
Li-3 protons Br-35 protons
The number of protons is the element's c) atomic number.
The symbol of a boron atom is "B", and the number of electrons in a neutral atom is the same as the number of protons, which equals the atomic number of boron: 5.
The number of protons of an atom is equal to its atomic number, and element number 79 is gold (Au).
The atomic number tells you the number of protons the atom of an element has. The atomis is the smaller of the two numbers next to symbol of the element.
The number of an element on the periodic table is equal to the number of protons in a single atom of that element. Since mercury (symbol Hg) has the atomic number of 80, this means there are 80 protons in a single atom of mercury.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
