NAMING ELEMENTS

The chemical symbol and the name of the elements must be known before starting any discussion in chemistry. There is a correlation between the name and the chemical symbol.

  • The chemical symbol is usually the first or the first and second letter of the name.

    H stands for the hydrogen atom

    He is helium Li is lithium

  • Or it could be the first and third letter

    Mg is magnesium Mn is manganese

  • Or it could be the letters for the “Old” (Latin, Greek, etc.) name

    Fe is iron (ferrum: latin) Cu is copper (cuprum)


Names of elements to know l.jpg
NAMES OF ELEMENTS TO KNOW

H = hydrogen atom Si = silicon Ag = silver

He = helium P = phosphorus Sn = tin

Li = lithium S = sulfur Zn = zinc

Be = beryllium Cl = chlorine Ar = Argon

B = boron Ba = barium Ni = nickel

C = carbon K = potassium (kalium) Pb = lead

N = nitrogen atom Ca = calcium Xe = xenon

O = oxygen atom Cr = chromium Au = gold

F = fluorine atom Fe = iron (ferrum)

Ne = neon Hg = mercury

Na = sodium (natrium) Cu = copper (cuprum)

Mg = magnesium I = iodine atom

Al = aluminum Br = bromine atom

NAMING ELEMENTS

  • There are 7 homonuclear diatomic elements.

    These elements do not exist “alone” readily under the conditions experienced on the surface of the Earth.

    H - hydrogen atom H2 - hydrogen

    N - nitrogen atom N2 - nitrogen

    O - oxygen atom O2 - oxygen

    F - fluorine atom F2 - fluorine

    Cl - chlorine atom Cl2 - chlorine

    Br - bromine atom Br2 - bromine

    I - iodine atom I2 - iodine

    You must be extra careful (& specific) when naming these elements
