Answer:
- you have to do maths in all 3
- atoms make up everything even parts of a cel and theyre studied in chem and physics
- chemistry is used in biology by finding out what different substances are eg cytoplasm in a cell

Answer:-
Metalloids
Explanation: -
Metalloids are elements with properties that are somewhat in between those that of metals and non metals. They have generally 4 or 5 electrons in their valence shell for up to the 4th period to be called a metalloid. From the fifth period 6 valence electrons can make an element metalloid.
From the sixth even 7 valence electrons can make an element metalloid
The electronic configuration of Germanium is
2,8,18, 4
So it is a metalloid.
The electronic configuration of tellurium,
2,8,18, 18, 6
So it is a metalloid.
The electronic configuration of Arsenic
2,8,18, 5
So it is a metalloid.
The electronic configuration of astatine
2,8,18, 32, 18, 7
So it is a metalloid.
Radius of atoms increase as you go down, can decrease from left to right in certain periods
