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:
D
Explanation:
There are 2 oxygens on the reactants side (OH)2 but 4 on the products side (2H2O). You cannot get 2 oxygens out of nowhere, so it is not balanced.
Answer:
Relative humidity is low .
Explanation:
The wet bulb reads low temperature because due to low humidity of atmosphere , evaporation of water takes place from the wet bulb which makes the bulb cool and therefore it reads lower temperature . In the process of evaporation , heat equal to latent heat of vaporization is taken from the bulb and it loses temperature.
