Which of the following is a true statement? A:Water expands when it freezes.
B:Water shrinks when it freezes.
C:Water loses mass as it freezes.
D:Water increases in mass as it freezes.

Hi there!

Your answer is:

B. Water shrinks when it freezes

Explanation:

When things are frozen, most commonly they shrink. This is due to the coldness calming down the atoms. When the atoms don't move as much, they get compressed together!

I hope this helps!

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
