chemistry help please!!!! answer this question i will mark brainliest
Answers
1.in an atom last shell electron is know as valence shell and if the last shell require any no of electron to complete octet or duplet is called valency of electron and noble gas are stable element the group 17 element becomes electron negative by ionisation by gaining the electron from the outermost shell and they require 8 electron to complete the octet ,atom requir 2 or 8 electron to complete either duplet or octet
kindly form the sentence according to your convenience
Answer:
In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.Noble gas configuration is the tendency of chemical elements to gain or lose electrons to reach the electronic configuration of a noble gas. This may refer to: Octet rule, the electronic rule for main group elements. 18-electron rule, the electronic rule for transition elements.Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.The Octet rule is a general rule of thumb that applies to most atoms. Basically, it states that every atom wants to have eight valence electrons in its outermost electron shell. All these terms are related to molecules.
