How many valence electrons may metals have?
Different metals have different numbers of valence electrons. The alkali metals have 1. The alkaline-earth, transition, and inner transition metals have 2. Aluminum and those in its column have 3, tin and lead have 4.
Tests to identify metals?
There are many different tests that can be used to identify different metals. Using a magnet is a popular test to distinguish metals.
How many different metals are conductors?
All metals are conductors of electricity and heat.

The two most commonly used metals in solder are?
The two most commonly used metals in solder are tin and lead. They are typically mixed together in different proportions to create solder with different melting points and properties for various applications.
What are 4 examples of metals?
Most commonly there are 6 different types of metals. These six include gold, silver, copper, lead, tin and iron.
Compare the solubilities of the lead compounds with those of the alkaline earth metals How are the solubilities similar and different?
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
What element poisons the brain?
Mercury, lead, and many other heavy metals.
What are the differences between pure metals and alloy metals?
they are different in many ways eg they are shinier
How many metals does lead have?
Lead is an element in the periodic system, (Pb). If it's pure, it doesn't contain anything else.
