use the periodic table to identify the element indicated by each electron configuration by typing in the…

Explanation:

Step1: Determine number of electrons

The sum of the exponents in the electron - configuration gives the number of electrons. For a neutral atom, the number of electrons is equal to the atomic number.

Step2: Identify element for $1s^{2}2s^{2}2p^{6}$

The sum of the exponents is $2 + 2+6=10$. The element with atomic number 10 is Neon, symbol Ne.

Step3: Identify element for $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$

The sum of the exponents is $2 + 2+6 + 2+3 = 15$. The element with atomic number 15 is Phosphorus, symbol P.

Step4: Identify element for $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{1}$

The sum of the exponents is $2 + 2+6 + 2+6 + 1=19$. The element with atomic number 19 is Potassium, symbol K.

Step5: Identify element for $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{8}$

The sum of the exponents is $2 + 2+6 + 2+6 + 2+8 = 28$. The element with atomic number 28 is Nickel, symbol Ni.

Step6: Identify element for $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{3}$

The sum of the exponents is $2 + 2+6 + 2+6 + 2+10 + 6+2 + 3=41$. The element with atomic number 41 is Niobium, symbol Nb.

Answer:

Ne P K Ni Nb
