The following is a list of electron distribution of atoms of unknown elements.Choose an element from the list for each of the following discriptions.(1) it is a noble gas (2) it is a soft metal with a low density (3) it has a giant covalent structure similar to diamond (4) it can form a negative ion of type X3-
Dear student
Please find the solution to the asked query:
i)Noble gas : Noble gases have 8 valence electrons in their outermost shell.
It is element D, with an atomic number 36 . the element is Kr , which is a noble gas.
ii)Alkali metals are soft and have one electron in its valence shell.
Element E is Rubidium which is a soft metal.
iii)Giant covalent structure similar to diamond is formed by elements belongong to group 14, which has 4 valence electrons. Element B forms this structure,The element is Silicon.
iv)the element which can form a negative io of the type X3- is element A. Element A in nitrogen, which can form an ion as N3-.
