Q

Julie loved hummingbirds and all summer long she would hang nectar feeders outside her windows and fill them with sugar water to attract those beautiful little flying jewels to her yard. She was always sad when winter came and her beloved hummingbirds would leave for warmer climes. Julie was feeling especially discouraged one cold and bleak winter day in January but comforted herself by thinking, “only three more months and my little friends will return bringing joy back into to my life!”

24
Q

Some people claim that fire is alive. Are they wrong?

Fire is not alive. To be classified as living, a thing must show all seven of the characteristics of life

Fire is not alive. To be classified as living, a thing must show at least 5 of the seven characteristics of life

Scientists do accept fire as living because it meets the standard of showing at least 4 of the seven characteristics of life

Fire is not alive. To be classified as living, a thing must show at least 6 of the seven characteristics of life

A

Fire is not alive. To be classified as living, a thing must show all seven of the characteristics of life

The number of neutrons

34
Q

This is sodium, a gentle and lovely little atom (just don’t expose to water or feed after midnight). How does sodium obtain a full valence shell? (only has one electron in the most outer shell)

A

It gives away an electron to other atoms

35
Q

This is sodium, a gentle and lovely little atom (just don’t expose to water or feed after midnight). How does sodium change when it gains a full valence shell?

A

It becomes a cation

36
Q

Water is a compound consisting of two hydrogen atoms and one oxygen atom. Why is water polar?

A

Electrons spend more time around the oxygen than around the hydrogens, giving the oxygen a partial negative charge and the hydrogens a partial positive charge
