Most of the elements on the Periodic Table are metals. They stretch from group 1 (far left) all the way to the "stair-step" that divides them from the non-metals. (Most periodic tables will show a stairstep-shaped pattern that begins between Po and At and goes diagonally up and left.)
Oxygen is in Group 16, Period 2. It's atomic number is 8. It's symbol is "O".The elements that surround oxygen on the periodic table are: N on the left, F on the right, He above it, and Si below it.
John newlands attempted to arrange the elements into the law of octaves but had got mocked by many peers
M means molar. Molar is how many moles per litre. The moles can be calculated by dividing the mass in grams by the molecular weight as seen in the periodic table
Arsenic -atomic number 33- is in the 4th period of Group 15 (or 5, when counting to max. 8), just below Phosphor (nr. 15) The electron configuration is (K,L,M,N orbits) => 2, 8, 18, 3
Krypton is a nonmetal.
H stands for Hydrogen in the periodic table
The M tells you which row of the periodic table you can find the element in, and the L tells you which suborbital the electron is found in. The suborbital signifies how many electrons are in the shell of the element.
The Lanthanides are a Period of Elements in the sixth period. They all metals. They all have variable oxidation states, but oxudation state '3' is the most stable. They lie in the Periodic Table between Group (II) (Alkaline Earth metals) and the Transition Metals.
Mg Uppercase M with a lowercase gAll elements and there symbols can be found in the Periodic Table
Yes! The elements on the right side of the periodic table are called metals and are the best conductors of electricity. The elements on the left are called nonmetals and they conduct heat and electricity the worst.

Oxygen is in Group 16, Period 2. It's atomic number is 8. It's symbol is "O".The elements that surround oxygen on the periodic table are: N on the left, F on the right, He above it, and Si below it.
The atomic mass of an element is listed on the periodic table, generally below the name of the element. The molar mass of a molecule will be generally be the sum of the atomic masses of the elements that make up the molecule.
Since we know the mass and molar mass, we can just insert them into this equation: n = m / M where n is the number of moles, m is the mass and M is the molar mass. I will not do the calculation for you, you should make your homework yourself (the molar mass of potassium can be found in the periodic table) :)
MX is the general formula where M is the alkali metal and X is the halogen.
2(IIA) Because The elements in Group 2 (IIA) are metals with a +2 oxidation state. Thus one atom of a Group 2 metal can combine with 2 atoms of chlorine (oxidation state = -1)
nM=m moles of solid multiplied by Molar mass (Atomic mass on periodic table) = Mass of solid
