• Masses of other atoms are expressed with respect to the atomic mass unit. For example, the mass of an atom of 1 H is 1.008 u, the mass of an atom of 16 O is 15.995 u, and the mass of an atom of 32 S is 31.97 u.
  • Atoms on row 1 have their valence electrons on the 1st energy level. Atoms on row 2 have their valence electrons on the 2nd energy level. Atoms on row 3 have their valence electrons on the 3rd energy level. This pattern repeats all the way through the end of the periodic table on row 7.

The Periodic Table gives you the atomic number of 17. Therefore there are 17 protons and 17 electrons. The arrangement of the electrons will be 2, 8, 7 (i.e. 2 in the first level, 8 in the second, and 7 in the third). The electronic arrangements of the first 20 elements Jul 03, 2019 · The modern periodic table is organized in order of increasing atomic number. The atomic number is how many protons an atom of that element contains. The number of protons is the deciding factor when distinguishing one element from another. Variation in the number of electrons or neutrons does not change the type of element.

A mole represents an extremely large number. Scientists use scientific notation to express extremely large or small numbers. The mass (in grams) of one mole of atoms of a substance can be found on the periodic table.

Distances on the atomic scale have traditionally been expressed in Ångstrom units (1Å = 10–8 cm = 10–10 m), but nowadays the picometer is preferred; 1 pm = 10–12 m = 10–10 cm = 10–2 Å, or 1Å = 100 pm. The radii of atoms and ions are typically in the range 70-400 pm. Some videos on atomic and ionic radii:

Dec 17, 2020 · Community Answer. The atomic mass, given in atomic mass units (amu), is generally very close to the atom's mass number. The mass number is found by adding the number of protons and neutrons in the atom. This number is based on Carbon-12, and as a result, Carbon-12 has an atomic mass of 12.

    H has a mass of 1.01 amu. This means that iron atoms are about 55.85 times heavier than hydrogen atoms. Atomic masses are always expressed as decimal fractions. One reason that they do not have whole number values is that, except for fluorine, atoms of the same element have different numbers of neutrons.

    Elements are classified according to their chemical properties and arranged into a chart called the periodic table. The smallest unit of an element is the atom. We used the periodic table to talk about the subatomic parts of an atom (the subunits of an atom) which are protons, neutrons, and electrons. Periodic Table The first accepted periodic table of elements was published in 1869 by Mendeleev. In the same year, a German chemist Lothar Meyer independently published a very similar table, but his contribution is generally ignored. All elements in the periodic table have been classified according to the electron configuration.
