Studdy Solution

STEP 1

1. Lewis dot structures represent the valence electrons of an atom.
2. Nitrogen and calcium are neutral atoms, so their electron configurations are based on their atomic numbers.

STEP 2

1. Determine the number of valence electrons for nitrogen.
2. Draw the Lewis dot structure for nitrogen.
3. Determine the number of valence electrons for calcium.
4. Draw the Lewis dot structure for calcium.

STEP 3

Determine the number of valence electrons for nitrogen:
- Nitrogen has an atomic number of 7. - The electron configuration for nitrogen is 1s22s22p31s^2 2s^2 2p^3. - The valence electrons are in the second shell: 2s22p32s^2 2p^3. - Therefore, nitrogen has 5 valence electrons.

STEP 4

Draw the Lewis dot structure for nitrogen:
- Represent nitrogen with the symbol "N". - Place 5 dots around the symbol to represent the 5 valence electrons. - Distribute the dots around the four sides of the symbol, pairing them as needed.

STEP 5

Determine the number of valence electrons for calcium:
- Calcium has an atomic number of 20. - The electron configuration for calcium is 1s22s22p63s23p64s21s^2 2s^2 2p^6 3s^2 3p^6 4s^2. - The valence electrons are in the fourth shell: 4s24s^2. - Therefore, calcium has 2 valence electrons.

STEP 6

Draw the Lewis dot structure for calcium:
- Represent calcium with the symbol "Ca". - Place 2 dots around the symbol to represent the 2 valence electrons. - Distribute the dots on opposite sides of the symbol.
The Lewis dot structures are now complete for both nitrogen and calcium.
