In order to find out how many electrons there are in an atom, look at the Atomic Number(also known as Proton Number). It's often found in the bottom left of an atomic symbol in the Periodic Table. Also, often in exams you will be asked to find the "Z" number of an atom, which is the same as the atomic number.
The number of protons and electrons equals because the in an atom must always balance -- in other words, the charge in an atom must always be neutral.
What else can I help you with?
The number of these is equal to the number of electrons in an atom?
A neutral atom has equal numbers of elecrons and protons.
Does the number of electrons in an atom give its atomic number?
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
What is equal to the number of protons which is equal to the number of electrons?
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
What is the relationship between the atomic number and the electrons in neutral atom?
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
Why is the number of protons equal to the number of electrons in an atom?
To maintain the neutrality of an atom the number of neutrons must be equal to number of electrons; in ions this number is not equal.
How would you figure the number of protons or electrons in an atom?
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
Number of electrons in a neutral atom of uranium?
A neutral atom of uranium has 92 electrons. This is because the number of electrons is equal to the number of protons in the nucleus of an atom, and an atom is neutral when the number of electrons is equal to the number of protons. Uranium has an atomic number of 92, which corresponds to the number of protons and electrons in a neutral atom of uranium.
How do the number of protons and electrons compare in a normal atom?
In a normal atom, the number of protons is equal to the number of electrons. This balance is necessary for the atom to be electrically neutral.
Which to particles in an atom are equal in number?
The protons and electrons are equal in number in a neutral atom
What two particles in an atom always have the same number?
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How many electrons are in an atom of elemental sodium equal to?
The number of electrons in a neutral atom is equal to the atomic number; sodium has 11 electrons. The number of protons is the same.
