By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.

The correct symbol for the isotope of potassium with 22 neutrons is k 41 19?
An isotope of potassium with 22 neutrons has an atomic number of 19 and atomic mass of 41. The symbol is K with a subscript 19 and superscript 41.
What are the correct symbols for the elements chlorine and iron?
Chlorine = Cl Iron = Fe
What is the correct chronological order of scientists contributing to the modern periodic table?
Lavoisier, Dobereiner, Newlands, Mendeleev, and Moseley
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
These particles are protons and neutrons; but to be correct the mass of electrons must be added.
What statements is not correct about the elements in a circuit?
a switch is rarely used in electrical circuits
Before scientists had the correct tools to look inside elements what did they use to draw conclusions about the structure of matter?
What tools did scientists use to look in to elements before they had the right kind of tools
How do you spell discovering?
the correct spelling is Discovered. Meaning as if to find something. hope this helped you.
What is the correct number of neutrons for Be?
Beryllium has 5 neutrons.
What are the atomic mass of elements rarely whole numbers?
1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers.2. Second cause: also occurs the so-called mass defect.Not atomic mass for elements; atomic weight is correct.
Do neutrons carry no charge?
Correct. Protons are positive, electrons are negstive, and neutrons have no charge
How do you spell neutrons?
That is the correct spelling of the plural noun "neutrons" (neutral atomic particles).
Do most elements occurs a mixture of two or more isotopes on nature?
For elements the correct term is atomic weight.For isotopes the correct term is atomic mass.The atomic weight is determined considering the isotopic composition of an element and the atomic mass of each isotope.
Is a nucleus made of of protons and neutrons?
Yes, it is correct.
Is it correct to say an atom with 4 neutrons and 4 protons has a nucleus with a charge of 4?
It is correct.
Do protons have positive charge neutrons have negative charge and electrons have no charge?
No, protons have positive charge, electrons have negative charge and neutrons have no charge
What is the correct representation of the isotope of sulfur that has 19 neutrons?
16S35
How many elements are in the periodic table as of 2012?
okay, so people commonly ask about the periodic table. The truth is scientists fought over this, so this answer may vary but, honestly there are 115-118 elements if you put any of those numbers you are correct.
