My teacher Mr. Ramdath taught me this short cut, but you need to know the Periodic Table..it's a secret ok don't tell it to much people..shhhhh ;) group number= number of rings period number= number of electrons

∙ 11y agoBy their definition, atoms have no overall net charge. That means that there has to be a balance between the number of positive protons and negative electrons.
The atomic number (shown in the upper left hand corner of the element's box), is also the number of protons the atom contains. This means that you have to also have that many electrons in order to make the atom neutral.
For example, Hydrogen's atomic number is 1, which means it has 1 proton. This means in order to make the atom neutral, it also has to have 1 electron!

∙ 13y agoIf it is the normal atom (not an ion) it will have the same number of protons and electons which will give it neither a positive nor negative charge.
To the left of the elemental symbol you have two numbers, the top number (which will be a larger value) is the mass of the atom, this is the sum of the protons and neutrons as electrons are deemed of negligible mass (1/2000).
The bottom number is the number of protons, as the atom is chargeless and proton = +1 charge; electron = -1 charge) this number will also be the number of electrons.

∙ 15y agoThe atomic number technically shows the number of protons, but in a balanced atom the number of protons is the same as the number of electrons.

What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
What atom number tells how many of these particles are in an atom?
The bigger number (Atomic mass) is the amount of protons (=same amount of electrons unless specified) and nutrons in an atom. The smaller number (atomic number) is the amount of protons only
What is the number on the bottom of each element's box called?
The little number under the Element symbol is known as the Atomic Number. The Atomic Number represents the number of protons located at the atom's nucleus. It also tells how many electrons are in the atom, considering the atom is a stable particle, the number of electrons and protons are equal in an atom at its normal state.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How many electrons are in the nucleus of an atom with the atomic number of 20?
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
How many electrons does each neutral chromium atom have?
24 electrons, remember the atomic number of an element tells you how many protons it has. The number of protons = the number of electrons (if the atom isnt charged)
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
What is the atomic number on a table that tells us how many of what are in an atom of the element?
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
How do electrons move from one atom to the next?

What is the equation use to find the amount of electrons are in fluorine?
The atomic number of an element tells you how many electrons there are and how many protons there are.
What is the mass number and atomic number of an atom?
Atomic number tells how many protons are inside an atom's nucleus and therefore also how many electrons the atom has. An atom's mass number is the number of protons AND neutrons in the atom's nucleus and this will vary for each isotope of an element.
Does the amotic number tell you how many protons an atom has?
Not really. You'd have to find the number of electrons first. Then do subtraction.The atomic number tells you how many protons and electrons the element contains
How is atomic number better than atomic mass?
Atomic Number tells you how many protons and electrons there are in a neutral atom.
How do you work out how many electrons in an atom?
An atom's atomic number is the number of electrons.
What two pieces of information does the atomic number give?
The atomic number gives you the number of electrons and protons there are in an atom. ex: Carbon (C) has atomic number 6. So we know that it has 6 protons and 6 electrons
How many electrons are in zirconium?
Zirconium is No. 40 in the Periodic Table. The '40' tells us the position of zirconium in the table, the number of protons in an atom , and the number of electrons in a neutrally charged atom. So the answer to you question is '40'.
