Number of valence electrons, that is, the number of electrons that the outer shell of an atom can hold. Ex. All halogens can have 7electrons in their outer shell. All gases have a full octet, eight electrons.
They are the same
Yes, they do (since they have the same number of valence electrons).
Family of elements share similar chemical properties due to having the same number of valence electrons. This results in comparable reactivity and bonding patterns within a group of elements. Additionally, they often exhibit a trend in physical properties such as atomic size and electronegativity.
They indicate groups of elements which often (but not always) share common properties. (cf. http://en.wikipedia.org/wiki/Periodic_table#Groups)One of the common characteristics in a group is that they share the same number of electrons on the outer shell.
Yes In Groups 1A through 8A
elements that share the same colum
Elements in a family or group of main group elements share similar chemical properties due to having the same number of valence electrons. This leads to comparable reactivity and the ability to form similar types of chemical bonds with other elements. Additionally, elements in the same group often show trends in physical properties such as atomic size and ionization energy.
Same elements of group have same valency. They possess same chemical behaviour.
elements that share the same colum
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
Elements in the same group as oxygen are sulfur, selenium, tellurium, and polonium. Group 16 elements are also known as the chalcogens and share similar chemical properties.
They are the same
culture
Elements of the same group generally share the same number of valence electrons, which are the electrons in the outer energy level only. These are the electrons that participate in a chemical reaction, so elements in the same group behave similarly in chemical reactions, which makes predictions and generalizations possible.
Yes, they do (since they have the same number of valence electrons).
Elements in the same family are related because of shared properties. For example, all the elements in the noble gas family do not react to anything and are colorless, nonflammable, odorless, and tasteless under normal circumstances.
Elements that have similar chemical properties occupy the same group on the Periodic Table.
