Question

periodic table literacy
understanding element tiles
before determining how atoms bond, we must be able to read the information provided on the
periodic table. study the examples of sodium (a metal) and carbon (a non-metal) below.
· atomic number: ____
· symbol: ____
· name: sodium
· atomic mass: _______
· atomic number: ____
· symbol: ____
· name: carbon
· atomic mass: _______
element analysis table
use a periodic table to find the following elements. fill in the missing data for each neutral
atom. remember: the group number (1-18) helps you determine the number of valence
electrons.
element name | symbol | protons | total electrons | draw electrons
chlorine | | | |
oxygen | | | |
nitrogen | | | |

Explanation:

Step1: Fill Sodium tile data

Atomic Number: $11$
Symbol: $\text{Na}$
Atomic Mass: $22.99$

Step2: Fill Carbon tile data

Atomic Number: $6$
Symbol: $\text{C}$
Atomic Mass: $12.011$

Step3: Fill Chlorine table data

Symbol: $\text{Cl}$
Protons: $17$ (equal to atomic number)
Total Electrons: $17$ (neutral atom: electrons = protons)
Electron drawing: 2 electrons in first shell, 8 in second, 7 in third

Step4: Fill Oxygen table data

Symbol: $\text{O}$
Protons: $8$ (equal to atomic number)
Total Electrons: $8$ (neutral atom: electrons = protons)
Electron drawing: 2 electrons in first shell, 6 in second

Step5: Fill Nitrogen table data

Symbol: $\text{N}$
Protons: $7$ (equal to atomic number)
Total Electrons: $7$ (neutral atom: electrons = protons)
Electron drawing: 2 electrons in first shell, 5 in second
