Because the number of protons and electrons are different in each element, which means that their chemical and physical properties are different.
Very different. Each element is unique.
No, each element is unique to its own properties, so each element has its own box/number
A period on the periodic table is a horizontal row that categorizes elements based on the number of electron shells they have. Each period corresponds to the number of electron shells an element's atoms possess.
The number with a decimal point in each element square on the periodic table represents the average atomic mass of that element. It takes into account the mass of different isotopes of the element and their relative abundance in nature.
A compound is simply different elements bonded to each other, in this case tin (Sn) and two fluorine atoms (F).
All are different. Each element has its own row and column that it fits into.
Yes, each element has a unique atomic number that corresponds to the number of protons in its nucleus. This atomic number determines the element's position on the periodic table and its chemical properties.
This number is different for each element and is equal to the atomic number of the element on the periodic table, i.e. carbon has 6 protons.
The period of an element in the periodic table indicates the energy level of its electrons. Each row in the periodic table represents a different period, with elements in the same period having the same number of electron shells.
The number listed above the symbol of an element on the periodic table is the element's atomic number.
Each element is represented by a one or two-letter symbol.
