The atomic number tells you the number of protons. For instance oxygen has an atomic number of 8, and hence it has 8 protons. Electrons are slightly more complicated. In a neutral atom, the number of electrons is always the same as the number of protons. However, if the atom is charged (i.e. it is an ion), it may have more electrons than protons (negatively charged) or less electrons than protons (positively charged).

How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How many electrons and protons are there in potassium?
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
What is the number of protons and electrons of berrylium?
The atomic number of beryllium is 4. The atomic number of an atom says how many protons are in that atom. In an unionized atom, the protons and electrons are the same amount. Beryllium (unionized) has 4 electrons and 4 protons.
An atom has what number of protons and electrons?
9 protons and 10 neutrons in F-19 isotope.
If an atom has 42 protons and 36 neutronshow many electrons will it have?
An atom is electrically neutral when the number of protons equals the number of electrons. Since the atom has 42 protons, it will also have 42 electrons, regardless of the number of neutrons. Therefore, this atom will have 42 electrons.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How many electrons has an atom?
An atom has the same number of electrons as it does protons, and the number of protons determines what element it is.
How many electrons and protons are there in potassium?
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
How many protons and electrons are contained in an atom of element ruthenium?
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
When an atom has seven protons how many electrons does it have?
Generally an atom has the same number of protons and electrons. Nitrogen has seven protons.
A certain atom has 8 protons and 10 neutrons. How many electrons does it have?
The number of protons in an atom is equal to the number of electrons. Therefore, an atom with 8 protons will have 8 electrons.
What is the number of protons and electrons of berrylium?
The atomic number of beryllium is 4. The atomic number of an atom says how many protons are in that atom. In an unionized atom, the protons and electrons are the same amount. Beryllium (unionized) has 4 electrons and 4 protons.
An atom has what number of protons and electrons?
9 protons and 10 neutrons in F-19 isotope.
What number is used to determine how many electrons are in a neutral atom?
The number used to determine how many electrons are in a neutral atom is the atomic number, which is the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is equal to the number of protons, thus balancing out the positive charge of the protons with the negative charge of the electrons.
If an atom has 42 protons and 36 neutronshow many electrons will it have?
An atom is electrically neutral when the number of protons equals the number of electrons. Since the atom has 42 protons, it will also have 42 electrons, regardless of the number of neutrons. Therefore, this atom will have 42 electrons.
An atom has 15 protons and 18 neutrons How many electrons does it have?
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
How electrons does a helium atom have?
2 electrons. The atomic number is the number of protons and however many protons there are, that is also the number of electrons.
