How do elements in the same family differ?
Element families are elements that have the same number of valence electrons. Most element families are a single column of the periodic table, although the transition elements consist of several columns, plus the elements located below the main body of the table.
How are the electron shells different from one another?
Electron shells consist of one or more subshells, and subshells consist of one or more atomic orbitals. Electrons in the same subshell have the same energy, while electrons in different shells or subshells have different energies.
Do elements in the same family have the same number of shells?
So, elements in the same group have similar chemical properties because they have the same number of electrons in their outer shell.
How do the different types of elements differ from each other?
The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. All the elements in the universe are arranged according to their atomic number in the periodic table.
Why do elements belonging to the same group or family have similar characteristics?
The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
Why do elements in the same family group have similar properties?
Because the members of each group in the main group elements has the same number of valence electrons, there are similar properties and similar trends in chemical reactions found in the group.
Is shell and Orbit same?
Orbit is a well-defined circular path around the nucleus in which electrons revolve around the nucleus. It is also called a shell. It is denoted by the principal quantum number ‘n’. Electrons can jump from one orbit to another by either absorbing energy or releasing energy.
What is the difference between shell and energy level?
Each electron shell has a different energy level, with those shells closest to the nucleus being lower in energy than those farther from the nucleus. By convention, each shell is assigned a number and the symbol n—for example, the electron shell closest to the nucleus is called 1n.
Why do elements in a group have similar properties while in period varies?
Elements in the same group have similar properties because they have the same number of valence electrons in their outermost shell. Elements in the same period have different properties because the number of valence electrons in their outermost shells differ.
