2. good conductor of heat and electricity
4. the quantitative measure of inertia
6. table is a tabular arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations and etc.
7. The ability of a measurement to match the actual value of the quantity being measured
9. the amount of space an object takes up.
10. refering to minutes , seconds hours
12. A measure of the rate at which a defined amount of matter
16. is the process observing and recording the observations that are collected as part of a research effort.
18. basic unit of an element
22. number the number of protons in the nucleus of an atom of an element
23. The halogens or halogen elements (/ˈhælədʒɨn/) are a group in the periodic table consisting of five chemically related elements, fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine
25. is an atom or molecule in which the total number of electrons is not equal to the total number of protons
26. has no charge
27. are atoms of the same element, having same atomic number but different atomic masses due to the difference in the number of neutrons present.
29. system is a system of measurement in a decimal form (each successive unit of measure is 10 times larger or smaller than the preceding unit). Its name is from the Greek (métron, to measure).
30. name the measure of one-dimensional objects

1. is a positively charged ion. Thus it has fewer electrons than protons. It is also attracted to the cathode in the process of electrolysis
3. is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element.
5. gravity the ratio of the density of a substance
8. metals comprise, at minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins.
11. Close, careful conformity to a convention, pattern, or objective standard in minute detail.
13. The act or state of being changed from one unit into another
14. negatively charge
15. is a measure of the thermal energy given off by moving particles
17. are the elements found along the stair-step line that distinguishes metals from non-metals
19. current (from Latin tellūs, "earth"), or Earth current, is an electric current which moves underground or through the sea
20. measurement is a definite magnitude of a physical quantity, defined and adopted by convention or by law, that is used as a standard for measurement
21. the force that gravitation exerts upon a body
24. is a way to measure how tightly packed an object is. Denser objects have less empty space in them
28. positively charge
