The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.

∙ 15y agoFor an atom, the number of electrons are equal to its atomic number. Atomic numbers can be obtained quite easily from the Periodic Table since elements are arranged according to their atomic numbers.

What is a cation and were can you find it in the periodic table of elements?
The periodic table contain neutral atoms not a list of cations; most metals are to right.A cation is an atom who lost electrons.
What is an anion and where can you find it on the periodic table?
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
What period on the periodic table of elements contains radioactive elements and what are they called?
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
What is the symbol and name for barium in the periodic table?
Ba. You'll find this in your copy of the periodic table of the elements.
How did other scientists find missing elements from the periodic table table?
truño hardisson
Why was it necessary to make a periodic table?
it is necessary to make a periodic table because it makes it easier to find elements that have similar physical characteristics and to find out the amounts of "shells" an element has of the amount of electrons on the elements vallence.
What does a periodic table have?
a modern periodic table should have the 118 elements, their atomic numbers, and their masses. to find the number of protons and electrons, they are the same as the atomic number. to find the neutrons, subtract the protons from the mass.
Where can you find the elements?
On a periodic table.
How do you find the most similar elements in the periodic table?
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
What is periodic in the periodic table?
The modern periodic table is modified form of the mossleys periodic table,which was yet modifiied form of the mendileevs periodic table,which was based on the principle-atomic mass is the periodic function of the elements.Mossley changed the periodicity of elements to be the periodic functions of their atomic numbers.hence in the modern periodic table we can find,the repeatation of certain properties of elements after definite intervals and hence the periodic table has groups and periods the elements inside which,are similar.this is possible because across a period electrons increase by 1,keeping shells sama,and down a group,outer electrons remain same,but shells increase by1.
What three facts about the elements can be derived from the periodic table?
You can find out what groups certain elements are in, and find there relative atomic masses. You can also find outy how reacticve they aRE AND HOW MANY ELECTRONS NEUTRONS AND PROTONS ARE IN CERTAIN ELEMENTS
How do you find Ka?
On the Periodic Table of Elements.
How many examples of the Periodic table can you find?
I can find only two types The Mendeleves Periodic table based on Atomic weight of elements and The Modern Periodic table based on Atomic number of elements.
What is a cation and were can you find it in the periodic table of elements?
The periodic table contain neutral atoms not a list of cations; most metals are to right.A cation is an atom who lost electrons.
What is an anion and where can you find it on the periodic table?

What period on the periodic table of elements contains radioactive elements and what are they called?
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
What is H2S on the periodic table?
You will not find H2S on the periodic table. The periodic table contains only elements, and H2S is a compound, made of two elements, hydrogen (H) and sulfur (S).
