Atoms of the representative elements
How do atoms attain noble gas electron configuration?
To attain a noble gas configuration, atoms combine with other atoms to complete their octet . Atoms attain noble gas configuration either by donating or obtaining and by sharing electrons present in their outermost shell. ... So atoms either gain or lose electrons to complete their octet.
How do atoms achieve noble gas configurations in single covalent bonds quizlet?
Atoms try to take on an electron configuration of a noble gas by transferring electrons . ... Atoms try to take on an electron configuration of a noble gas by sharing electrons.
Why do atoms want to attain noble gas configuration?
Covalent bonds are mainly formed due to the tendency of the elements to attain a completely filled outer shell , that is, attain noble gas configuration and become stable. ... In covalent bonds, when two atoms are in need of extra electrons to fill their outer valence electron shell, they will often share an electron.
What is the noble gas configuration?
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons . So for sodium, we make the substitution of [Ne] for the 1s 2 2s 2 2p 6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3s 1 .
Why do atoms combine?
Atoms mainly combine to fill the outermost shell and they can combine with similar elements or different elements. Sometimes, they can achieve stability even after half-filled subshell. ... Electrons that are present in the outermost shell are known as valence electrons.
How do atoms achieve a noble gas electron configuration in single covalent bonds?
Answer: Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms , unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.
How many electrons does carbon need to gain to get a noble gas configuration?
It requires 8 electrons because that is the amount of electrons needed to fill a s- and p- orbital (electron configuration); also known as a noble gas configuration. Each atom wants to become as stable as the noble gases that have their outer valence shell filled because noble gases have a charge of 0.
How do atoms achieve a complete octet in single covalent bonds?
Atoms of nonmetals form covalent bonds by sharing electrons in order to achieve an octet of valence electrons, like the noble gases, except for helium, which only has two valence electrons.
Do noble gasses have low energy?
Noble gases are the least reactive of all known elements . That’s because with eight valence electrons, their outer energy levels are full.
Why does every element want to be a noble gas?
Every element wants to achieve stability which is possible only when they got fulfilled outer most shell thats why elemennt wants be have noble gas configuration. ... Noble gases have maximum number of valance electrons that their outer shell can hold. Hence they attain near stable state.
What is the difference between electron configuration and noble gas configuration?
An electron configuration is the sequence of electrons that are present in an atom. The key difference between noble gas configuration and electron configuration is that noble gas configuration has only electron pairs whereas an electron configuration can have both paired and unpaired electrons .
How do atoms stick together?
Why exactly do atoms tend to combine together? ... Atoms form chemical bonds with other atoms when there’s an electrostatic attraction between them . This attraction results from the properties and characteristics of the atoms’ outermost electrons, which are known as valence electrons.
Which type of bond is weakest?
The ionic bond is generally the weakest of the true chemical bonds that bind atoms to atoms.
