For a neutral atom they must have equal numbers of protons and electrons. The atomic number is the number of protons in an atom of an element. Find the atomic number by looking at the Periodic Table of elements.
What else can I help you with?
How do you determine the number of electrons in an atom?
The number of electrons in an atom is determined by the atomic number of the element, which is the same as the number of protons in the nucleus. Electrons are negatively charged particles that balance the positive charge of protons in an atom.
How many electrons does C-12 have?
A carbon-12 atom has 6 electrons. The atomic number of carbon is 6, which determines the number of electrons in a neutral carbon atom.
Electrons within a pure atom are equal to what?
The number of protons in the nucleus of the atom. This is because in a neutral atom, the number of electrons is equal to the number of protons in the nucleus, which maintains overall electrical neutrality.
How many electrons does sulfur-33 have?
Sulfur-33 has 16 electrons since it is a neutral atom and the number of electrons is equal to the number of protons in the nucleus for a neutral atom.
What information about the subatomic makeup of an atom is given by the atomic number?
The atomic number of an atom gives the number of protons in its nucleus, which also determines its unique identity as an element. It also indirectly gives the number of electrons in a neutral atom, as the number of protons is balanced by the number of electrons in the atom.
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
How do calculate the number of electrons in neutral atom poses?
Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.
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.
How you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass number?
the atomic mass number is the number of protons/electrons in an atom
How do you calculate electrons in an atom?
Reference the atomic number of the atom on the periodic table. The electron count is generally equal to the number of protons
How do you calculate number of electrons of a given element?
You can only be sure of the number of electrons if the element is electrically neutral. If an element is electrically neutral, then the number of electrons is the same as the number of protons which is the atomic number of the element. For instance an electrically neutral atom of carbon, there are 6 electrons because there are 6 protons in a carbon atom.
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
How do you calculate formal charge?
to calculate the formal charge:Take the number of valence electron the neutral atom would have (found on the periodic table) and subtract it from the number of electrons in lone pairs +1/2 of the number of electrons in bonds
How can you calculate the number electron in an atom?
The number of electrons in a neutral atom is the same as the atomic number of the atom and is listed for each element in the Periodic Table found in any basic chemistry text book.
How do you calculate number of electrons required for the reaction?
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
