f. 11 electrons, very reactive with water
g. the lightest element
h. toxic metal with 80 protons
j. very light metal, 13 electrons
n. needed for strong bones
o. atomic mass of 24.3

Explanation:

• A: Chlorine has atomic number 17 and is used to kill bacteria, so it matches Chlorine Green.
• B: Bromine has an atomic mass of approximately 79.9, so it matches Bromide Brown.
• C: Carbon has atomic number 6 and is crucial for life, so it matches Carbon Red.
• D: Helium makes balloons float, so it matches Helium Brown.
• E: Nitrogen has atomic number 7 and makes up about 78% of the atmosphere, so it matches Nitrogen Blue.
• F: Sodium has 11 electrons and is very reactive with water, so it matches Sodium Blue.
• G: Hydrogen is the lightest element, so it matches Hydrogen Blue.
• H: Mercury has 80 protons and is a toxic metal, so it matches Mercury Brown.
• J: Aluminum has 13 electrons and is a very - light metal, so it matches Aluminum Brown.
• N: Calcium is needed for strong bones, so it matches Calcium Yellow.
• O: Magnesium has an atomic mass of approximately 24.3, so it matches Magnesium Orange.
