What is the charge of chlorine atom If you subtract the number of electrons from the number of protons?
–1
Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. It is now referred to as a chloride ion.
How do you find the net charge in chemistry?
Net charge is the sum of all formal charges of the atoms in a molecule. Net charge is the charge of the molecule. Example: I take the example given previously with NO3−, in order to give a complete answer to the present post. Sum the valence electrons of all atoms.
What is the charge for chlorine?
−1
Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.
How do you calculate protons and electrons?
To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.
How are the number of protons and electrons in an atom determined?
A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. You can find the number of neutrons if you know the isotope of the atom.
How many electrons and neutrons does an element have?
It has 10 electrons, 10 fundamental negative charges. Since the element is neutral, it has 10 fundamental positive charges, 10 protons, in its nucleus. In the nucleus there are also 12 massive, neutral particles, 12 neutrons.
How many protons are needed to make an atom neutral?
If the element has 10 electrons and has a net charge of 0 which makes it a neutral atom, the atom must have 10 protons. Elements are defined by the number of protons which is also equal to the atomic number. #10^+ =# Atomic Number 10.
What kind of charge does an atom have?
An atom has 10 electrons, 12 neutrons, and no net charge. What element is this atom, and what are its atomic number and mass? Hmmmm, Z = 10, the element is not fluorine, and its not sodium. If you are doing your chemistry homework, you must have a Periodic Table beside you.
