the group 2/ii elements are known as the alkaline earth metals. answer the following true or false questions about them.
be is not a metal 1
they like to lose 2 electrons 2
they like to form cations 3
when they lose their two electrons, they are attracted to anions 4
a. true b. false

Explanation:

1. Beryllium (Be) is an alkaline - earth metal, so "Be is not a metal" is false.
2. Group 2 elements have 2 valence electrons and tend to lose them to achieve a stable electron configuration, so "they like to lose 2 electrons" is true.
3. When they lose electrons, they form positively - charged ions (cations), so "they like to form cations" is true.
4. Opposite charges attract. When they lose 2 electrons and become cations, they are attracted to anions, so "when they lose their two electrons, they are attracted to anions" is true.

Answer:

1. B. false
2. A. true
3. A. true
4. A. true
