Answer:
Hydrogen is usually classified as a group 1 element since it has one valence electron, just like group 1 metals.
Explanation:
Answer:
1. Option A. Beta decay minus 0 -1e
2. Option B. Alpha 4 2He
3. Option A. Beta decay minus 0 -1e
Explanation:
1. 66 29Cu is undergoing beta decay minus since it produces a daughter nuclei having the same mass number and the atomic number increased by 1 i.e 66 30Zn
2. 238 92U is undergoing alpha decay since the daughter nuclei produced has a decrease of 4 in the mass number and a decrease of 2 in the atomic number ie 234 90Th
3. 14 6C is undergoing beta decay minus since the daughter nuclei produced has the same mass number and the atomic number increased by 1 i.e 14 7N

Liquids are similar to gases in that they both have <span>no definite shape.</span>
Option #2 because gas can take up a lot of space and the particles can spread out more. think of fog its a gas and it can spread out over a big area and its hard for the sun to shine through enough to heat it up and evaporate it.<span />
