The nuclear symbol of an isotope indicates the number of protons and neutrons in an atom of the element. It does not indicate the number of electrons.
What does the bottom number in a nuclear symbol represent?
Explanation: The atomic number is the number of protons present in the nucleus of an atom. This number does not change without changing the element. In elemental notation, the atomic number is found at the bottom left corner of the chemical symbol for the element.
What does the 4 represent in the nuclear symbol of the helium isotope?
Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Since 2 + 2 = 4, we know that the mass number of the helium atom is 4.
What is the nuclear symbol of chlorine?
Chlorine is a chemical element with symbol Cl and atomic number 17. Classified as a halogen, Chlorine is a gas at room temperature.How are nuclear symbols written?
To write a complete nuclear symbol, the mass number is placed at the upper left (superscript) of the chemical symbol and the atomic number is placed at the lower left (subscript) of the symbol. … This mass difference results from nuclei of the same element having a different number of neutrons.

What does atomic number represent?
atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

What is the nuclear symbol for uranium 238?
Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons. Its symbol is U23892 (or 238U).
What is the symbol of radon?
radon (Rn), chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium.
What is the difference between uranium 235 and 238?
Uranium-235 and U-238 are chemically identical, but differ in their physical properties, notably their mass. … The U-238 nucleus also has 92 protons but has 146 neutrons – three more than U-235 – and therefore has a mass of 238 units.
