I got the answer: 1s2 2s2 2p6 3s1 3p6 4s2 3d10 4p1Why isn't the shorthand of this (Zn) and valence electrons of Gallium hereApparently the shorthand is [Ar]4s23d104p1 and I DON'T KNOW WHY, explain clearly for 10pts as i'm just starting chemistry
Shop around for a used craneThere are a couple of boatyards where I'm at that haven't had any issues with their cranes, except for one operator error incident.
When using shorthand you always use the previous noble gasThe noble gases are the elements in the last group (column) of the periodic table (group 18)We use them because they naturally have a full outer electron shellFor gallium, and every other element in that period (row across the periodic table), the previous noble gas is Argon eg, for Aluminium 1s2 2s2 2p6 3s2 3p1 you'd write [Ne] 3s2 3p1
I'm most familiar with marina's that use travel-lift equipment to move boats as neededHowever, given the size of your space and the size boats you will be working on, I think a fixed crane coupled with wheeled cradles would make the best use of spacea Forklift is a possibility, but you'd need maneuvering room for ether the travel lift or forkliftOn a hard surface, like a concrete pad, roll-able cradles would allow boats to be moved easily yet packed tightlyI've seen stiff-legcranes that would be half as expensive as a travel lift.
