(a)
Interpretation:
The minimum number of electrons that would have to be added and the minimum number that would have to be removed to change the electronic configuration of the given element to get a noble gas configuration are to be indicated.
Concept introduction:
Every element wants to attain an electronic configuration same as noble gas configuration, to do so elements either gain electrons or lose electrons. When an atom of an element gains electrons, it forms an anion. When an atom of an element loses electrons, it forms a cation.

Interpretation:
The minimum number of electrons that would have to be added and the minimum number that would have to be removed to change the electronic configuration of the given element to get a noble gas configuration are to be indicated.

- A monatomic ion with a 2 charge has the electron configuration 1s22s22p63s23p64s23d104p6. a What neutral noble gas atom has the same electron configuration? b What is the monatomic ion with 2 charge that has this configuration reaction? c Write the symbol of an ion with a 1+ charge that is isoelectronic with the species in a and b.arrow_forwardWhen potassium and chlorine react and form an ionic compound, why is there only one chlorine atom for each potassium atom instead of two?arrow_forward• use electron configurations to explain why metals tend to form cations whereas nonmetals tend to form anions.arrow_forward
- A monoatomic ion with a charge of 1 has an electronic configuration of 1s22s22p63s23p6. a Is this ion a cation or an anion? b With what noble gas is it isolectronic? c What is the symbol of the ion?arrow_forwardFirst you need to find the number of valence electrons in NH2Cl. For counting purposes with Lewis structures, the number of valence electrons in an atom of a main group element is equal to the last digit in the group number of that element in the Periodic Table. N is in Group ________ H is in Group ________ Cl is in Group _________ In NH2Cl there is a total of ____________ valence electrons.arrow_forwardFor each of the following ionic compounds, predict the chemical formula using their position on the periodic table.arrow_forward
