25 Questions

1.
a substance made up of atoms of two or more different elements joined by chemical bonds

2.
Any characteristic of a substance, such as flammability, that indicates whether it can undergo a certain chemical change

3.
A table that shows the elements, their atomic number, symbol, and average atomic mass; elements with similar chemical properties are grouped together.

4. matter that does not have a definite shape or volume

5.
an element that has some characteristics of metals and some characteristics of nonmetals, found along the zig zag line.

6.
a combination of two or more atoms

7.
tells the number and type of elements in a compound

8.
a chemical substance that is present at the start of a chemical reaction

9.
an element that is solid at room temperature, a good conductor of heat and electricity, and generally is shiny; most metals are ductile and malleable; found to the left of the zig zag line.

10. that which has mass and occupies space

11.
the principle stating that matter is not created or destroyed during a chemical reaction

12.
negatively charged particle; located outside the atomic nucleus

13.
A chemical reaction that absorbs energy from its surroundings

14.
a chemical reaction in which heat is released to the surroundings

15.
a characteristic that can be observed or measured without changing the identity of the substance

16.
a chemical substance formed as a result of a chemical reaction

17.
a region of an atom in which electrons of the same energy are likely to be found

18.
(chemistry) a substance consisting of two or more substances mixed together (not in fixed proportions and not with chemical bonding)

19.
a solid that forms from a solution during a chemical reaction

This is

20. any of the more than 100 known substances (of which 92 occur naturally) that cannot be separated into simpler substances and that singly or in combination constitute all matter

21.
Vertical column of elements in the periodic table

22.
A number written below and to the right of an atomic symbol in a chemical formula that tells the number of atoms in a molecule or the ratio of elements in a compound.

23.
a horizontal row of elements in the periodic table

24.
element that usually is a gas or brittle solid at room temperature, is not malleable or ductile, is a poor conductor of heat and electricity, and typically is not shiny; found to the right of the zig zag line.

25.
a subatomic particle that has no charge and that is found in the nucleus of an atom
