Non-metals have a larger number of outer electrons called valence electrons. Therefore, it is easier for them to "steal" valance electrons from other elements with fewer valence electrons(usually metals)
For example, Chlorine(Cl) has 7 ve-. When forming an ion it will steal one electron from a metal. and gain a charge of -1. Because the ion is NEGATIVELY charged, it will be called an anion.
Nonmetals form anions.
Vocab:
cation: Paws-itively charged ions (get it? because its a CAT ion?)
anion: negatively charged ions
Answer:
35.45 amu is the average atomic mass of chlorine.
Explanation:
The average atomic mass is given :
Atomic mass of 35-Cl = 34.968 amu
Percentage abundance of 35-Cl = 75.53%
Fractional abundance of 35-Cl = 0.7553
Atomic mass of 37-Cl = 36.956 amu
Percentage abundance of 37-Cl = 24.47%
Fractional abundance of 37-Cl = 0.2447
Average atomic mass of chlorine:
35.45 amu is the average atomic mass of chlorine.
Answer:
3, because H2 ×3 =6, and if you plug in a two in NH3 it would be equal
Answer:
eye wash: if you get chemicals in your eyes it helps to clean it
chemical/safety shower; If chemical gets on your skin everywhere you need to take a shower immediately so it helps you get rid of the chemicals on your skin
fire extinguisher: if something cashes on fire you need that to extenguish it
Explanation:
1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it
2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth
3) mass and how far away you are from the object
4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)
5) when distance increases, gravity decreases (again I do not remeber by how much)
