Is there any pattern to the way the three metals react with water?
The reactivity of metals with water often follows a general trend based on their position in the periodic table. Alkali metals, such as sodium and potassium, react vigorously with water, producing hydrogen gas and a hydroxide. Alkaline earth metals, like calcium, react less vigorously, while transition metals typically show little to no reaction with water. Thus, the pattern indicates that reactivity decreases from alkali metals to transition metals.
What group would lithium be in on the periodic table?
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.
Why is hydrogen not part of the alkali metal or halogen chemical family?
Hydrogen is really in a category by itself; it isn't normally considered an alkali metal. Some periodic tables put it at the top center of the chart (that is, not in any of the groups) to emphasize that.
Are alkali metal and alkaline earht metals similar?
Alkali metals and alkaline earth metals are both groups of elements found in the periodic table. They have similar characteristics in that they are both highly reactive, low-density metals with low melting points. However, alkali metals are located in group 1 of the periodic table, while alkaline earth metals are located in group 2, and they have different chemical properties and reactivities.
Where is the alkali metals located on the periodic table?
The alkali earth metals are in the 2nd group, or column of the Periodic Table. They are bordered by the alkali metals on the left and the transition metals on the right.

What group are in alkali metals in?
Alkali metals are a group of metals located in Group 1 of the periodic table. They include elements such as lithium, sodium, potassium, and rubidium. Alkali metals are highly reactive and typically form ionic compounds with other elements.

What is the malleability of hydrogen?
Hydrogen is not malleable in the same way that metals are. It is a gas at room temperature and does not exhibit the same physical properties as solid materials like metals.
Where is the alkali metals located on the periodic table?
The alkali earth metals are in the 2nd group, or column of the Periodic Table. They are bordered by the alkali metals on the left and the transition metals on the right.
What due know the position of hydrogen in the periodic table and also write down similarities and dissimilarties with 1 group 4A AND 7A?
Position of hydrogen in periodic tablePosition of an element in periodic table depends upon its electronic configuration and properties. Hydrogen resembles the elements of group I-A, IV-A and VII-A in some respects. Properties of hydrogen do not completely match any one of the above-mentioned groups. That is why position of hydrogen is still undecided.Resemblance Of Hydrogen With Alkali Metals(Group I-A)1) Like alkali metals hydrogen has one electron in its valence shell.ExplanationH (Z=1): K1Li (Z=3): K2, L1Na (Z=11): K2, L8, M1(2) Both require just one electron to complete their valence shells.3) Both hydrogen an alkali metals are good reducing agents.4) Like alkali metals hydrogen can also form halides.Explanation: Hydrogen:HCl, HI.I-A:NaCl, KBr.5) Halides of alkali metals and hydrogen ionized in similar way in aqueous solution.Explanation:HCl (aq) è H+(aq) + Cl-(aq)NaCl(aq) è Na+(aq) + Cl-(aq)6) Like alkali metals hydrogen can also form compounds with non-metals.Explanation:I-A:Na2SHydrogen:H2S7) Both lose electron to form positive ions. E.g. H+, Na+8) Alkali metals and hydrogen belongs to s block.DIFFERENCES :-1) Hydrogen is a non-metal where as elements of I-A are metals.2) Hydrogen can form both covalent and ionic compounds. But alkali metals only form ionic compounds.3) Hydrogen can gain an electron to form H- ion.4) Hydrogen is a gas at room temperature but alkali metals are solids.5) Unlike Na+ or K+ hydrogen ion (H+) is unstable in water.Explanation:H+ + H2O è H3O+6) Alkali metals do not occur freely in nature due to their high reactivity but hydrogen does occur.7) Hydrogen occurs in diatomic state (H2).8) I.P. of hydrogen is very high as compared to alkali metals.Resemblance of Hydrogen with Carbon Family (IV-A)1) Valance shell of hydrogen is half-filled like the elements of group IV-A.Explanation:H (Z=1) : Capacity of K-Shell =2 , no. of electrons = 1 , % = 50%C(z=6) : Capacity of L-Shell = 8 , no. of electrons = 4 , % = 50%2) I.P. and E.A. of hydrogen and carbon are comparable.3) E.N. of H and Carbon family are almost similar. [H = 2.1, C = 2.5 , Si= 2.4]4) Both show reducing effects.Explanation:CuO + H2 è Cu + H2OSnO2 + C è Sn + CO25) Both combine with other elements through covalent bonding.ExplanationDIFFERENCES1) Carbon is tetravalent but Hydrogen is a mono-valent.2) Hydrogen is a gas at room temperature but elements of group IV-A are solids.3) Boiling and melting points of hydrogen is very less than that of the elements of group IV-A.Resemblance Of Hydrogen With Halogens1) Both Hydrogen and Halogens require one electron to complete their valence shell.2) Both hydrogen and Halogens are non-metals(Except iodine which has partial metallic character).3) Both hydrogen and Halogens acts as negative ions when combined with metals. 4) Their molecules are diatomic.5) Like Halogens, hydrogen can also form both ionic and covalent bond.ExplanationHydrogen:NaH (ionic),CH4 (Covalent)Halogens:NaCl (ionic), HCl6) Both H and Halogens form compound with metals and non-metals.ExplanationHydrogen :H2S [S=non-metal]Halogens : HCl [H = non-metal]DIFFERENCES1) Hydrogen has one electron in valence shell while Halogens has seven electrons.2) Electronic configuration of H = 1S1,Valence shell electronic configuration of Halogens = nS2, nS53) Unlike X- ion, H- ion is unstable in water and reacts in the following manner.ExplanationH- + H2O èH2+ OH-UNIQUE ATOMIC STRUCTURE OF HYDROGEN:Hydrogen is the only element which has no neutron in its nucleus.ConclusionDue to above reasons it is clear that hydrogen cannot be placed in any one of the above mentioned groups.
What are other elements in the hygrogen family?
Hydrogen isn't really in a "family". It's a little bit like the alkali metals and a little bit like the halogens, but it's not exactly either of those things.Personally, I consider the hydrogen "family" to be: hydrogen, full stop.It's possible the author of your textbook disagrees, in which case he or she is wrong, but your teacher may not see it that way, so you probably should try reading your textbook for the answer given there before relying on my response.
What is a substance that gives up hydrogen in a chemical reaction an alkali or a base oran acid or a metal?
A substance that gives up hydrogen in a chemical reaction is typically an acid. Acids are compounds that release positively charged hydrogen ions (H+) when dissolved in water. Alkalis, bases, and metals do not necessarily give up hydrogen ions in the same way.
Is Ibuprofen an acid or an alkali?
Actually, it's both. It's got a basic hydroxyl group sticking out there, and an acidic hydrogen on that Nitrogen atom. But not very strong one way or the other...
Why do alkali metals in group 1 react the same way to water and oxygen?
Alkali metals are highly reactive because they have little electronegative affinity for their own valance electrons and so donate them readily to elements and molecules with greater electronegativity, or molecules with constituent element with greater electronegativity.
