Answer:
Which Element am I? Directions. Identify the element that corresponds to each of the following electron configurations.
1. PHO S PHORUS (P)
2. ARGON (A r)
3. POT A SSIUM (K)
To calculate the electron configuration for phosphorus (P), which is in the third ro w, p-block, third element in that block, write: 1s 2 2s 2 2p 6 3s 2 3p 3. Check your work by adding the electron numbers to see if they equal the atomic number of the element; for this example, you would write: 2+2+6+2+3=15, which is the atomic number of phosphorus.
