Why are alkali metals so unstable?
They are very reactive. They can react violently or explosively with water, usually catching fire soon after contact. They react with moisture and air to produce strong bases that can cause serious chemical burns. The two most reactive of the metals, rubidium and cesium, burst into flames on contact with air.
What are the differences between alkali metals and transition metals?
1.Both are differ in valency shell electrons 2.I-A are monovalent and II-A are divalent 3.I-A is more reactive then the II-A group . 4.I-A have more electro positive character and II-A have less electro positive character than the I-A group . 5.I-A have less ionization energy and II-A have high ionization energy than the I-A . 6.I-A have very less electro negativity than the II-A group elements. 7.I-A is soluble in water and II-A is insoluble in water . 8.I-A metals are does not react directly with nitrogen but II-A react with nitrogen directly. 9.I-A group elements are strong reducing agents than the II-A group elements. 10.The oxidation values are differ. 11.I-A obtained in solid state but II-A group in solution state 12.Decomposes on heating I-A give only oxygen but II-A group liberates both oxygen and nitrogen .

How many transition metals are in period 3?
There are 8 transition metals. Elements from V to Cu belong to this.
Where does unreactive metals go in the periodica table?
The least reactive metals are those of columns 8, 9, and 10 in periods 5 and 6.
What does rcra stand for?
It stands for the Resource Conservation and Recovery Act. It determined acceptable levels for certain metals in our environment, and was written back in 1976. It specifically monitors levels of 8 different metals that have special environmental concerns. Those metals, called the RCRA-8 metals, are arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver.
Role of river in meeting the city water needs?
class-8
Are water trucks class b?
Truck classification isn't concurrent with the license required to drive them. A single axle water truck could be a Class 5, 6, 7, or 8 truck, depending on the vehicle GVWR. A Class 7 or Class 8 truck would require a (minimum) Class B CDL.

BA-8 Personal water craft are considered what type of motor vessel?
Class A
14 properties of metals?
1. All metals lose electrons however gold can form aurides. 2. All metals conduct electricity. 3. All metals do metallic bonding. 4. All metals have free electrons. 5. All metals react with fluorine. 6. No metals are gases at RTP, there're either liquid (caesium, gallium, mercury) or solid. 7. Nearly all metals are shiney silver in colour except copper, gold and osmium. 8. All metals are at least fairly good conductors of heat. 9. All metals form atleast 1 compound soluble in water. 10. All metals have atleast 1 full s subshell This is way to broad of a question to possibly get 14, there are many different groups of metals the s block metals which are split into alkali and alkali earth metals, transition metals, poor metals, rare earth metals which are split into lanthanoids and actinoids.
Characteristics of non metal?
1.Non-metals are mostly liquids or gases but some are found in solid state.2.Non-metals are usually non-flexible.3.It is difficult to to mold non-meats and convert them into wires and sheets.4.In non-metals atoms are bonded by covalent bonds.5.Non-metals are usually non-conductors but few of them conduct electricity.6.Non-metals are easy to cut or break.7.Non-metals do not transfer heat.8.Non-metals do not have much brightness even on polishing.9.Non-metals do not absorb light.10.Non metals are usually light in weight and have low density.11.Non-metals usually have low melting and boiling points.12.Non-metals ion bear negative charge but some bear positive charge as well e.g.Hydrogen.13.Oxides of Non-metals are acidic.14.Non-metals have tendency to accept electrons.15.Non-metals do not react with water at room temperature.16.Non-metals rarely react with acids
