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
What else can I help you with?
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 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.
If the atomic number of an Atom is 11 how many electrons does Atom have?
You cannot know for sure withoutmore information. An electrically neutral sodium atom (sodium has at. no. 11) will have the same number of electrons as protons; atomic number tells you the number of protons, so this atom has 11 protons and would have 11 electrons if electrically neutral, however, if the atom is charged, it could have more or fewer electrons. Sodium atoms in stars are highly ionized and may have just a few if any any electrons.
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 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
How do electrons move from one atom to the next?

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
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.
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 calculate the number of valence electrons in an atom?
To calculate the number of valence electrons in an atom, you look at the group number of the element on the periodic table. The group number tells you how many valence electrons the atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
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 do I find the valence electrons in an atom?
To find the valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
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'.
