1. What atom and symbol matches this electron configuration? 1s22s22p63s33p64s23d104p65s24d105p66s24f145d9 A. Silver( As) B. Germanium(Gu) C. Copper(Co) D. Gold(Au) 2. The number of Valence electrons in an atom with an electron configuration of 1s2 2s2 2p6 3s2 3p4 is... A. 6 B. 2 C. 16 D. 4
Expert Solution
Step 1

The electronic configuration is written in 

nlx method

n = principle quantum number

l = azimuthal quantum number

x = number of electrons

In neutral atom , number of electrons represent atomic number of element.

From electronic configuration we can find atomic number and symbol of element by counting the number of electrons.

The electrons which ars present in outermost shell are called valence electrons.
