Humans do not require nitrogen, generally. But nitrogen in the atmosphere is important to modify oxygen in the atmosphere. In the context of "too little" nitrogen in the atmosphere, the result can cause the ignition of almost every combustible on Earth, needing only a lightning strike to trigger it! Worse for humanity, if nitrogen in the atmosphere dropped from its present (approx. 78%) ratio down to 67%, lightning in the atmosphere would create nitrous oxide, killing all humanity in minutes! Not to worry, though, long before that happened, the first calamity would already have occurred! But feel better - The most common usage of "too little" nitrogen is regarding soil. Too little nitrogen can turn green lawns into yellow. Nitrogen is the most important element in soil fertility, and is basic to chlorophyll, necessary for foliage (including trees) to create oxygen for us all.
Yes, helium is lighter than nitrogen. Helium is the second lightest element, while nitrogen is a bit heavier due to its molecular structure. In fact, helium is the lightest noble gas and is commonly used in balloons for this reason.
The nitrogen family comprises of the group 15 elements which consist of nitrogen, phosphorous, arsenic, antimony and bismuth. All these elements have five valence electrons.
Not possible to say as there are too many formulas for different inks.
If there is too much nitrogen in the environment, it can lead to nutrient imbalances in the ecosystem, causing issues like algal blooms in water bodies, decreased oxygen levels, and disruption of the natural balance of plant and animal populations. Excessive nitrogen can also contribute to air pollution and global warming through the release of nitrogen oxides.
