Why do you think amorphous metals can be stronger than metals with grain boundaries, if grain boundaries can often strengthen materials?
aluminum has 13 protons in its nucleus, which are positively chargedTo balance the charges, we need 13 negatively charged electrons in orbitals around itSo a neutral atom of aluminum will have 13 electrons.
13 Aluminum is neutral (unless it's some weird aluminum isotope.)
14 electrons are always the same amount as neutrons hope this helps xxxxxxxxxxx
13 - same as no of protons if its neutral
amorphous metals tend to be stronger than crystalline alloys of similar chemical composition, and they can sustain larger reversible (elastic) deformations than crystalline alloys Amorphous metals derive their strength directly from their non-crystalline structure, which does not have any of the defects (such as dislocations) that limit the strength of crystalline alloys Amorphous metal is usually an alloy rather than a pure metalThe alloys contain atoms of significantly different sizes, leading to low free volume (and therefore up to orders of magnitude higher viscosity than other metals and alloys) in molten stateThe viscosity prevents the atoms moving enough to form an ordered latticeThe material structure also results in low shrinkage during cooling, and resistance to plastic deformation The absence of grain boundaries, the weak spots of crystalline materials, leads to better resistance to wear and corrosionAmorphous metals, while technically glasses, are also much tougher and less brittle than oxide glasses and ceramicsThermal conductivity of amorphous materials is lower than of crystalsAs formation of amorphous structure relies on fast cooling, this limits the maximum achievable thickness of amorphous structureshope this will help you,.
