Do group 1 metals contain reactive or unreactive elements and why?
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
Why give two reason why hydrogen should not be considered as group 1 element?
Hydrogen is a gas at room temperature, while all the other group 1 elements are solids, and hydrogen forms covalent bonds much more readily than any other group 1 element.
How do physical properties differ as you move across a period or down a group?
Moving down a group, the elements will have the same number if valence electrons. Tis will give them similar properties, such as the Noble Gases, or the extreme reactivity of Group I metals. Moving across a period, elements will begin to resemble each other less and share fewer properties the further apart they are in the row.
What elements are most likely to give up electrons rather than share electrons?
The ones on the far left (except hydrogen).
Why group 1 elements become positive after they react with other elements?
because they almost always give away a valance electron during bonding

Give an example of how hydrogens characteristics set apart from other group 1 elements?
Hydrogen is an alkali metal just like all the other elements in group 1. The difference is that hydrogen is a nonmetal and a gas which seperates it from the rest of group 1's elements. The rest of the elements in group 1 are metals and solid. (this was done by #41 for all u ppl at sjs who have no idea what the hell this worksheet was about.)

Does helium contain hydrogen?
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.

Which group of elements wants to give away 2 electrons?
group 2
What group of elements on the periodic table give electrons?
Metals give electrons.
What are the elements that are found in stars?
Stars are basically made of 2 elements - hydrogen and helium. Since their temperatures are extremely high, the hydrogen atoms fuse to give helium, thus producing light.
What three elements are found in nitric acid?
Nitric acid is not actually only one element! It is a compound of three elements in order to give this acid. The elements are: Nitrogen, Hydrogen and Oxygen. Hence, Nitrogen Hydroxide: Nitric Acid!
What elements will most likely give up a single electron to bromine?
The group 1 elements, which are the alkali metals.
Why can hydrogen be placed in either group 1 or 7 on the periodic table?
Hydrogen can be in both group 1 and group 7 due to it's valence shell. Hydrogen only needs 2 (or 0) electrons to be stable. Because it has 1 electron, it can either accept one (like a group 7 element) or give one away (like a group 1 element). It can act like either group.
What element is combine to produce base?
Li, Na, K etc., 1st group elements Ca, Ba etc., 2nd group elements, give the strongest bases
