In King Kong, Skull Island is located at approximately 12Â°S 78Â°E / 12Â°S 78Â°E / -12; 78 â somewhere off the coast of Sumatra. There is a distinctive rocky knoll in the center of the island which is shaped like a human skull, hence its foreboding name.
Best Answer: All Br atoms have 35 protons (the atomic number of Br). Since 81 is the mass number (sum of protons + neutrons), this atom has 81-35 = 46 neutrons. An uncharged atom of bromine will have the same number of electrons as protons. Since this atom has a -1 charge, it has one additional electron. So, it has 36 electrons.
The Atomic Number of an element is always equal to the number of protons. The Mass Number of an element is equal to the protons added to the neutrons. The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. Therefore. An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.
