Write the election configuration for an atom of Beryllium___. On the back, draw the electron orbital diagram for Sodium. In the electron configuration model, which subshell will accept the next electron after the 4s is filled?___. Which is the first element to contain full p subshell ?___. Which of the element is found in Period 4 and is a member of Group 17?___. On the back, write out the electron configuration for Strontium. The electron configuration of a particular element is 1s2 2s2. Name an element that has similar chemical properties?___. Name an element that has an electron configuration that ends in p5.___. An element ending in an electron configuration s1 would be classified as an___.Explanation / Answer
6.
An atom containing x proton, y neutron and x electron it mass number is = x + y
because mass number is sum of no. of proton and neutron.
11.
five d orbitals fit in forth level
because there are 10 electron in d each orbital occupy 2 lectron thus there is 5 orbitals in forth d level.
16.
3d orbital filled after filling 4s
because orbital are filled by increasing energy level 3d orbital have higher energy than 4s orbital and lower energy than 4p orbital therefore 3d orbital filled after filling 4s
17.
Neon (Ne) is first element contain full p subshell
because it contain 10 electron and it electronic configuration is 1s22s22p6
