The compound water, H2O is made of hydrogen and oxygen, both non-metals.
The names of elements on the periodic table are not capitalized unless they are at the beginning of a sentence or part of a proper noun. For example: "hydrogen" not "Hydrogen."
A positive ion, which is the same thing as "an ion with a positive charge", is called a "cation".
Yes, C4H10 is a molecular formula representing butane, which is a type of hydrocarbon molecule. It consists of four carbon atoms and ten hydrogen atoms bonded together.
Be stands for Beryllium in the periodic table of elements. It is a light and strong metal that is commonly used in aerospace and defense industries due to its high stiffness-to-weight ratio.
Sr stands for strontium on the periodic table of elements.
Americium-243 might undergo alpha decay to become neptunium-239, and here is that equation:
95243Am => 93239Np + 24He++
The americium-243 has undergone transmutation to become neptunium-239, and the alpha particle, which is a helium-4 nucleus, can be seen on the tail end of the equation.
One component of gunpowder is sulfur, which is responsible for lowering the ignition temperature of the mixture. Another component is charcoal, which provides fuel for the combustion reaction. The third component is potassium nitrate (also known as saltpeter), which is the oxidizing agent that provides oxygen for the combustion process.
Bromine, like Fluorine and Chlorine, is an Halogen. Halogens gain an electron to become X^(-) anion.
'X' being the general symbol for an halogen.
No, it is the last member of Carbon family.
Mercury (Hg ; Hydragyrum).
It is only one of two elements that are liquids are STP.
Mercury is also known as 'Quicksilver'. Becasue a spot of it on a glass surface is impossible to pick up (quick) added to which it is silvery in solour, hence its name 'Quicksilver'.
You can have the alcohol functional group (-OH) on the end of the chain or or it can be on any carbon in the chain .
e.g.
CH3CH2CH2CH2CH2OH ( pentan-1-ol)
CH3CH2CH2CH(OH)CH3 ( pentan-2-ol)
CH3CH2CH(OH)CH2CH3 ( pentan-3-ol)
#1 ; Atomic Number (position in the Periodic Table.
#2 ' The Atomic Mass
#3 ; The number of protons and electrons (Same as Atomic Number)
#4 ; The groups and periods of elements.
#5 ; The Physical state ( solid, liquid , or gas).
Bismuth sulphate.
NB
The formula should be written as Bi2(SO4)3 . Note the use of the brackets, otherwise it indicates that there are '43' oxygen atoms in the molecule.

Water.
Remember the equation
Moles = mass(g) / Mr (Relative Molecular Mass)
So Molar Mass(g) is = to moles X Mr.
or
Mr = mass(g) /moles
Since ther mass is 18 g and molar mass is 1 mole
Then substitute
Mr = 18g / 1 = 18
So referring to the Periodic Table. for elements with an atomic below 18 .
We have oxygen at 16 and hydrogen at 1
So 16 + 1 + 1 = 18
.
Hence oxygen + 2 hydrogen = water (H2O).
Chlorine!!!
Chlorine has two stable isotopes ; Cl-35 & Cl-37
The subatomic particle arrangemtn in them is
Cl-35 ; 17 protons, 18 neutrons, 17 electrons
Cl-37 ; 17 protons, 20 neutrons, 17 electrons.
'Na' is Sodium. The use of 'Na'. comes from the Latin name for sodium , which is 'Nadium'
Similarly
'K' is Potassium. The use of 'K'. comes from the Latin name for potassium , which is 'Kalium'
NB There are a number of other elements in the Periodic Table, where the symbol does not indicate the modern name.
