Take a look at the shells, each has a certain number electrons orbiting the central nucleus, in the case of the Nobel Gases, they all have 8 electrons except of course for hydrogen which has 2. Each ring has a certain number of electrons which causes the atom to be more stable than others. The outermost is called a valence electron shell. In the case of the Nobel Gases it causes the element not to be as reactive to other substances. Depending upon how many electrons are in the outer shell, will denote how reactive an atom will be. Those atoms with only 1 electron, will be quite non reactive where as those that are missing just one electron from making it complete will be quite reactive.
They have the same outer electron structure.
What else can I help you with?
What is similar when elements have the same group?
Elements in the same group have similar physical and chemical properties.
Do elements in the same group or period have similar properties?
Elements in the same group have similar properties because they have the same number of valence electrons. In contrast, elements in the same period do not necessarily have similar properties, as their chemical behavior is determined by the number of electron shells they have.
Are elements with similar chemical properties found in the same group om the periodic table?
Yes, elements with similar chemical properties are often found in the same group on the periodic table. This is because elements within the same group have the same number of valence electrons, leading to similar reactivity and chemical properties.
Do elements in the same group have the same physical or chemical properties?
Elements in the same group have similar properties as they have the same number of valence electrons.
Do elements in the same group have similar atomic numbers?
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
Why do the elements in a group of the period table have similar properties?
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Which elements have similar properties on the periodic table?
Elements in the same group or column on the periodic table have similar properties. This is because they have the same number of valence electrons, which determines their chemical behavior. For example, all elements in Group 1 (such as lithium, sodium, potassium) share similar properties due to having one valence electron.
Do any of the elements on the periodic table of elements have similar properties?
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
How are elements in the same group similar?
Elements thare are in the same goup have similar phsyical and chemical properties.
What elements have similar chemical and physical properties.?
elements in the same group
The properties of elements in a in the periodic table are often similar?
Elements in the same group have similar properties because they have the same number of valence electrons. This influences their chemical behavior and reactivity. Elements in the same period have similar atomic size but vary in other properties due to the changing number of electron shells.
Do elements in the periodic table have similar properties?
No. All elements in a same group have the same number of valence electrons and hence have similar properties.
