Consider the elements in this family (group) of the periodic table. because they are in the same family, what can you predict about these elements? a) they are all about the same mass. b) they are chemically reactive in a similar way. c) the size of the atom decreases as you go down the column. d) the elements change from metals to nonmetals as go down the column.

Option (B) is the correct answer.

Explanation:

Elements of same group tend to show similar chemical properties because elements of same group show same number of valence electrons.

Therefore, they have similar chemical properties.

For example, nitrogen and phosphorous are both group 15 elements and they show similar chemical properties.

Thus, we can conclude that because they are in the same family, we can predict about these elements that they are chemically reactive in a similar way.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
