Question

• Scandium, a transition metal, is added to aluminium to create an alloy used in aluminum bats and bicycle frames • Determine the number of protons, neutrons, and electrons present in 4.Sc. Reserved

Answer 1

first we will discuss scandium an we will discuss seet a . ...... upper number is mass adomic number is atomic number .....n lower to equal atomic is always A no. of proton ma number, both in case aloms or of neutral ou lons. Boohooooo lonized is o no. of nue dron equal alloma in or difference number and mass atomic say atomic mass - no. of proton - we can . Both no. of neutron in case of lons and neutral ondom to number of no of electron is equal in neutral anom proton are equal to in lons no electron of number of proton - charge

for more clarification we will compare asso 45 3+ se c nel 21 45 3+ se no. of proton = 21 no. of proton = 21 no. of no. of neutron = 45-21 neutron = 45-21 = 24 = 24 no. of electron = 21 - (+3) = 21 7 no .of. electron - 18 (equal to number of piston) (number of prodon - cho of then number electron s negative, (NB) If the equal charge is to number of proton - proton & charge.
