One of the properties of alkali metals is that they dont react with water?
False!
How many electrons do the alkali metals have in their outer energy shell?
If you are referring to the alkali metals of Group 1, such as sodium and potassium, the answer is no - in fact with a valence of 1 they are short 7 electrons in their outer level, which is why they react so readily (and violently) with the halogens, chlorine, fluorine and so on.
Is lithium behaves different from the other alkali metals true or false?
True. Although lithium is an alkali metal it is quite different from the other alkali metals. In fact it can generally behave more like an alkaline earth metal, such as Magnesium (Mg), Calcium (Ca) Strontium (Sr) and Barium (Ba). One of the major characteristics of the alkali metals is their low ionization energy, which is why lithium can easily be present in its ionic form of Li+. However, lithium posses the highest ionization energy of the alkali metals
In single replacemant reactions metals lower on the activity chart replace higher metals on a higher chart true of false?
False
Diatomic elements are generally stable when they are in molecular form true or false?
false

False!

Is it true or false that hydrogen is considered to be a metal?
Hydrogen is a non-metal. Hydrogen is a colorless, odorless, and tasteless gas that is the most abundant element in the known universe. It is the lightest and simplest having only one proton and one electron. Although hydrogen has an ns1 electron configuration just like alkali metals, it is still not metal because it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than other alkali metals. Because hydrogen is a nonmetal and forms H–(hydride anions), it is placed above the halogens in the periodic table. Hydrogen also forms H2dihydrogen like halogens. However, hydrogen is very different from halogens. Hydrogen has a much smaller electron affinity than halogens.
What is more stable partially filled or full electron shells?
Atoms with full outer electron shells are more stable. The atoms (elements) with full outer electron shells are the noble (sometimes called inert) gases. These are the elements in Group 18 of the periodic table, and you know them as helium, neon, argon, krypton, exnon and radon.
Is the following sentence true or false All elements easily form compounds with other elements?
False. Many elements easily react, such as those in the Alkali Metals and Alkaline Earth Metals, VI, and halogen groups. Other elements react only under the right conditions, such as the transition metals. Some elements, such as the noble gases, do not react or react only under very stringent conditions.
Is the following sentence true or false hydrogen servers as the final electron acceptor of the electron transports chain?
False
Is Soil a chemical solution of metals?
false
Hydrogen serves as the final electron acceptor of the electrons transport chain true or false?
False. Oxygen serves as the final electron acceptor of the electron transport chain.
True or False Elements of the halogen family lose one electron to become halide ions?
false; it reacts so that they acquire the electron structure of a noble gas.
Do common metals have the property of being ductile or is this false?
This would be false.
In single replacemant reactions metals lower on the activity chart replace higher metals on a higher chart true of false?
False
