No, non-metal elements can form both positive and negative ions. Non-metals tend to gain electrons to achieve a stable electron configuration, resulting in the formation of negative ions.
A negative ion is a molecule with a negative electrical charge. The number of electrons and protons in negative ions is not equal. In the human body, they help alleviate depression because they increase the level of serotonin in the body.

The elevation of 2400 feet is approximately 731.52 meters above sea level.
It has both effects. The affect of low level ozone is certainly negative. Breathing issues for the elderly or those with health issues is bad. High altitude ozone helps us keep the planet warm (global warming) and filters out much of the ultra violet radiation that would otherwise hurt us.
Yes, that is correct. Altitude above sea level, for example, is negative or positive - if you are below sea level, a negative number will be used.
For example:If having cash is a positive number, having a debt is a negative number (you are worse of than if you simply don't have anything).Similarly, gaining a profit on a transaction is positive; losing money is a "negative profit". The same can be said for the mathematical expectation (expectation value) of any activity, bet, game, etc.Altitude above sea level can be called positive, below sea level, negative.
If an altitude above sea level is positive, then an altitude below sea level is negative.If having money is positive, having a debt is negative.If gaining money is positive, losing money is negative (a negative gain).If an increase in speed is a positive acceleration, a decrease in speed is a negative acceleration.Any other similar case, where you define one thing as positive, and its opposite as negative.

Positive integers can represent elevations above sea level, while negative integers can represent elevations below sea level. For example, an elevation of 500 meters above sea level can be represented by the integer +500, while an elevation of -200 meters below sea level can be represented by the integer -200.
We can use negative numbers and positive numbers in: Sea level- If the sea level is below or above the ground Money- If you are in debt with someone Temperature- If the temperature is below or above 0 Points- If you are winning or losing someone Weight- If you loss or gain weight Maps- If you are going north, south, east or west Time- If you arrive early or late Floors- If you are below ground level or above ground level
Whenever you have two opposites, you can use positive number for one, and negative numbers for the other. For example: * Having money might be positive, owing money might be negative (owing money is worse than just having nothing). * Getting money might be a positive change; spending money (or otherwise losing it), a negative change. * Places above sea level might be assigned a positive altitude; places below sea level, a negative altitude. * If latitudes north of the equator are defined as positive, then latitudes south of the equator would be negative. Or the other way round.
At the basic level, the modulus of a number or expression is simply the value of the number or of the expression. For a positive number the modulus is the number, for 0 it is 0, and for a negative number, x, it is -x (which is positive).
Whenever you have quantities or measurements in two opposing directions, you can label one of them as positive, the other as negative. One clear example is money - you can have money (positive), or you can owe money (negative). Your amount of money in a given month can increase (positive), or it can decrease (a "negative increase"). Another example is altitude above sea level - when you are BELOW sea level, you can use a negative number to express your "altitude above sea level". As to "rational" - most countries use a main currency (for example, U.S. dollar) and a fractional part thereof (for example, cents). Similarly, the altitude above sea levels is usually expressed in meters; but you can express smaller increments in fractions or decimals.
Use positive numbers for altitudes above sea level, zero is sea level itself, and negative numbers for altitudes below sea level. As for the picture, use a number line - but make vertical instead of using the commonly used horizontal position.
The number for sea level would be 0. Everything above it is a higher number and everything lower is a negative number.
For example, an altitude above sea-level can be expressed as a positive number; below sea-level is negative.Or: If you have money, you have a positive amount of money; if you owe money, that goes against you, you have "less than nothing", so it can be expressed as a negative amount.In technology and science - would you classify that as "real-world"? - negative numbers are used all the time. For example, if you decide that moving in a certain direction (e.g., "up") is positive, a movement in the opposite direction is negative.
