What else can I help you with?
Is Magnesium a metal from the lanthanide series or actinide series?
Neither. Magnesium is an alkaline earth metal (group II).
Being a lightweight with a high melting point this group II metal is an ideal hardening agent?
Beryllium is the lightweight Group II metal with high melting point that is known for its use as a hardening agent in various alloys.
Is Pb II a metal?
No, it is not. It is a group 14 element, a post-transition metal.
What group II metal is a hardening agent in alloys?
Iron alloys are hardened by carbon, Manganese or Molybdenum, Chromium, Titanium, Nickel, Boron, Cobalt
What is the symbol equation for metal and oxygen?
Use the letter 'M' . The number of oxygen atoms in the metal oxide depends on the Group in the periodic table. Group (I) = M2O Group(II) = MO Group (III) = M2O3 Group (IV) = MO2 The transition metal have variable oxidations. They can be M2O, M2O3 , MO, M3O4
Which alkaline earth metal is the hardest?
Beryllium is the hardest element in group II, at 5.5 on the Mohs scale. The hardnesses decrease as you go down the group, until barium has a hardness of 1.25.
How many moles of OH ions are produced from the hydroxides of group ii metals for every mole of the base that dissociates?
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
Is RbCl soluble or insoluble?
Soluble. All Group (I) metal (Alkali metals) are soluble. All Chlorides and Nitrates are soluble. Group (II) & (III) cations have a greater tendency to insoublity . Sulphates, phosphates and hydroxides are insoluble, unless combined with a Group(I) metal ion.
How many molecules of OH ions are produced from the hydroxides of group II metals for every molecule of base that dissociates?
For every molecule of a group II metal hydroxide that dissociates, two hydroxide ions (OH⁻) are produced. This is because group II metal hydroxides, such as magnesium hydroxide (Mg(OH)₂) and calcium hydroxide (Ca(OH)₂), dissociate in a 1:2 ratio, releasing two hydroxide ions for each formula unit. Thus, for each molecule of base that dissociates, two OH⁻ ions are generated.
When was The Metal Opera Part II created?
The Metal Opera Part II was created on 2002-10-29.
Who was the first metal group ever?
Korn is the first Nu Metal group that they were labelled as Nu Metal.
Is berylium a metal nonmetal or metalloid?
Beryllium is a metal. It belongs to alkali metal group or group 2.
