What can be concluded if an ion of an element is smaller than an atom of the same element?
(1) the ion is negatively charged because it has fewer electrons than the atom.
(2) the ion is negatively charged because it has more electrons than the atom.
(3) the ion is positively charged because it has fewer electrons than the atom.
(4) the ion is positively charged because it has more electrons than the atom.

The question is,'what can be concluded if the ion of an element is smaller than the atom of the same element'. The correct option is 'the ion is positively charged because it has fewer electrons than the atom. An atom becomes charged either by donation or accepting electrons. When an atom donate electrons, it becomes positively charged and it has less electrons than its atom. For instance, calcium has 20 electrons, it becomes an ion by donating its two electrovalent electrons, thereby having only 18 electrons left. But when an element accepts electrons, it becomes negatively charged and has more electrons than its atom.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .

First adhesives: hide glue.  which is made by boiling raw hides and bones or fish skins and bladders.other first adhesives: asphalt/tar, pitch/plant sap, and even blood.hope that : )
