Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon);
one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine). Metalloids such as boron, silicon, and germanium are sometimes counted as nonmetals.
ANSWER:
Liquid:
Bromine - Br - 35
Solid:
Carbon - C - 6
Phosphorus - P - 15
Sulfur - S - 16
Selenium - Se - 34
Iodine - I - 53
Answer:
Iron, or Fe, has 26 electrons, with two electrons in the outer valence shell. Iron is a transition metal and is both lustrous and easy to work with. Iron is also prone to rust, especially in damp environments. Iron is a ferrous metal, meaning that it can be magnetized.

srry i cant solve this ill tey to get people to answer the question and if they don't know ill learn it and answer for you
Answer: 14.01 moles
To solve this question, you need to determine the molecular mass of the Ba(OH)2. The molecular mass would be: 137.3 + 2(16+1)= 171.3g/mol.
If the total weight of Ba(OH)2 is 2400g and its molecular mass is 171.3g/mol, the number of moles would be: 2400g/ (171.3g/mol)=14.01 moles
