Use the following key to classify each of the elements below in its elemental form: A. Discrete atoms ...
B. Molecules ...
C. Metallic lattice
D. Extended, three-dimensional network
1. Argon
2. Bromine
3. Nitrogen
4. Fluorine

Discrete atoms

Argon

Molecules

Bromine

Nitrogen

Fluorine

Explanation:

The existence of substances in the elemental form depends on the nature of the substance.

Argon is a noble gas hence it seldom participates in chemical combination therefore it exists as discrete molecules in elemental form.

Bromine, fluorine and nitrogen all exist as diatomic gases because they combine readily with each other to form elemental molecules. An elemental molecule is a molecule composed of the atoms of the same element.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
