An elements symbol is an abbreviation of a chemical element, which makes it easier to read the Periodic Table if you know your abbreviations for each element as it won't be so cluttered. The atomic number is the number of protons found in the nucleus of an atom. In an atom of balanced/neutral charge, the Atomic Number is the number of electrons.

Europium, with the chemical symbol Eu, is the chemical element with the atomic number 63.
What elements on the periodic table are usually identified with three things?
Elements such as oxygen, silicon, and carbon are commonly associated with three things: atomic number, atomic mass, and chemical symbol. These properties help uniquely identify each element on the periodic table.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.

What information is included in each square of the periodic table of elements?
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
What does the atomic symbol?
1. The number of a chemical element in the Periodic Table. 2. The number of protons of this chemical element. 3. The number of electrons (in neutral state) of this element. 4. Also the atomic number is proportional to the atomic weight.
What three things are elements on the periodic table usually identified as?
Elements on the periodic table are usually identified by their atomic number, atomic symbol, and atomic weight. The atomic number represents the number of protons in the nucleus, the atomic symbol is a one- or two-letter abbreviation for the element, and the atomic weight represents the average mass of the element's atoms.
What element has 121.75 as it's atomic weight?
The element of Antimony (Sb) would have the atomic weight of 121.75.
How do you draw a model of the atomic box with atomic number 16 symbol Si and atomic weight 28.0855?
To draw a model of the atom with atomic number 16 and symbol Si, you would have a nucleus at the center with 16 protons and 16 neutrons. Around the nucleus, you would have 16 electrons orbiting in various energy levels, following the rules of electron configuration. The atomic weight of 28.0855 indicates the average weight of the isotopes of silicon.
