Where is mass number and atomic number when an element is represented in symbolic way?

Answer 1

Answer potassium is number 19

The atomic number, the number of protons in an element, is shown at the bottom left hand corner of the element, whereas the mass number is shown at the top left hand corner of the element. The mass number shows the number of protons+neutrons in the element

Answer 2

Atomic number is the number of an element in the Periodic Table of Mendeleev; it is equal to the number of protons and electrons (in a neutral atom). The symbol is Z.

Mass number is the sum of neutrons and protons in the nucleus of an isotope.

The symbol is A.

Answer 3

It's not, really. That is, atomic number 1 has symbol H, but there isn't any "rule" for determining what the symbol is given the atomic number; you just have know them.

Some of the synthetic transuranic elements do not have formally recognized names or symbols yet, and there IS a systematic naming scheme for these; the symbol will have three letters, and each letter will represent one of the digits in the atomic number (0 = n, 1 = u, 2 = b, 3 = t, 4 = q, 5 = p, 6 = h, 7 = s, 8 = o, 9 = e). So a hypothetical element with Z = 134 would have the symbol Utq.

Answer 4

It is not.

The atomic number refers to the number of electrons or protons in an atom of the element. Its symbol depends on the name of the element in English or, sometimes, in Latin.

Answer 5

The atomic no is left side down an Atomic Mass is at upper side, as for sodium 11Na23, 11= atomic no and 23= atomic mass.

Answer 6

Between the atomic number and chemical symbol any relation exist.
