atomic no. 31. GALLIUM

There is no central globe in this element. Fig. 99. Funnels. Gallium has six similar funnels, each with two segments. Segment A. There is first a cone of 7 Anu, then three rather curiously formed groups of fifteen Anu. containing a P9 group and an N6. The three upper spheres. Ga20. in segment A are made up of two Be4 and two H3 in the form of a cross with an Ad6 in the centre.

Segment B is somewhat similar to segment A. It contains first a B5 instead of the cone, then three groups Gal3, made up of P9 and Be4. and then a row of three spheres. Gal8, each with four H3 in the form of a cross with N6 in the centre. Segment B contains 98 Anu.

Total 1260 Anu

atomic no. 33. ARSENIC

Funnels. All six funnels are alike, and there are not two separate segments. Arsenic resembles Aluminium in having eight internal sub-divisions in the funnels, and the ovoids which form the top ring are identical with those in Aluminium save for the minute difference that in Aluminium the ovoids stand the reverse way from those in Arsenic. In Arsenic the top and bottom triplets in the top ovoids point downwards and the middle one upwards, in Aluminium the opposite is true. Arsenic inserts sixteen spheres, in two rows of eight, between the ovoids and the bottom globe A1.9', which is similar to that in Aluminium. Each of these 16 spheres contain nine Anu, N9, so that Arsenic adds no less than 144 Anu to each funnel of Aluminium. The total in one Arsenic funnel is 225 Anu.

THE CUBE GROUP B INDIUM

Funneb. Each of the six funnels has three segments instead of two. and the segments are of two types. Three funnels contain two segments of type A and one of type B ; the other three funnels contain two segments of type B and one of type A. Segment A is similar to segment A of Gallium, save in the substitution of a body of 16 Anu for the cone of 7 Anu, making a total of 121 Anu. Segment B is similar to the B segment of Gallium save that a body of 14 Anu, Inl4, is substituted for the B5 group, making a total of 107 Anu.

Type A funnels contain 2A-+-B. Type B funnels contain A+2B.

Antimony is very similar to Indium. There is no central globe. Fig. 100. Funnels. As in Indium there are two types of funnels and each funnel contains three segments, of types A and B.

Segment A consists of seven bodies. Nearest the centre we find a group containing two quintets and a septet L7. This group may be identified as Sbl7'. Then comes a ring of three spheres containing 17 Anu, Sbl7. In this sphere we find that the unit in the centre of the P9 group has been replaced by a triplet. Finally there is another ring of three globes each containing two triplets, two quartets and an Ad6. This is Ga20. This whole segment is Sbl28. Segment B also contains seven bodies, first a group of three small spheres which is identical with Inl4. then a ring of three Sbl5, and finally three Gal8, the whole making Sbll3.

So in Antimony we find three funnels of Type A containing 2A + B segments and three funnels of Type B containing A+2B.

Total = 2169 Anu

Number weight = 120.5
