Why elements have different number of electrons?
In a neutral atom the number of electrons is equal to the number of protons; and the number of protons is the label of a chemical element.
Equal to the number of protons in an atom found on the periodic table?
The atomic number or the number of electrons is equal to the number of protons.
If you only know the number of electrons can you determine the element?
No; not if it is an ion. A chlorine atom, for example, has 17 protons and 17 electrons, but a chlorine ion (like when it is in sodium chloride, which is table salt) has 17 protons and 18 electrons. So, if you see an element with 18 electrons, it could be a chlorine ion, an argon atom, or a potassium ion.
What are quantities that are always equal to an elements atomic number?
The atomic number is the number of protons, and, in a neutral atom, also the number of electrons.
Is the number of valance electrons equal to the atomic number?
The number of valence electrons is equal to the atomic number for elements in groups 1, 2, and 13-18 on the periodic table. This is because these elements have their valence electrons in the same energy level as their atomic number. However, this is not true for elements in transition metals (groups 3-12), as the pattern becomes more complex due to the filling of inner d orbitals.
Which element has the total number of electrons is equal to the number in chlorine?
Potassium, with 19 electrons, has the same count as chlorine which also has 17 electrons.
How many electrons are in a chlorine 36?
the number of protons is always equal to the number of electrons only then the atom will be stable hence there are 17 electrons in chlorine 36
How many are there electrons in Chlorine?
Chlorine has 17 electrons. The number of electrons in an electrically neutral atom is equal to its atomic number (the number of protons in the nucleus of the atom). The electronic configuration of chlorine is [Ne] 3s2 3p5.
Who many electrons are in the element chlorine?
17 same number as protons equal charge balance
How would you use the Periodic Table to find out how many electrons are in a chlorine atom?
To find the number of electrons in a chlorine atom, you look at its atomic number on the Periodic Table. Chlorine has an atomic number of 17, which means it has 17 electrons since the number of electrons in an atom is equal to its atomic number.
How many total electrons are present if the atom is electrically neutral in chlorine?
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
Why elements have different number of electrons?
In a neutral atom the number of electrons is equal to the number of protons; and the number of protons is the label of a chemical element.
What is number of electrons in chlorine?
To find this out, we'll look at a period table to find chlorine's atomic number. This tells us its number of protons, which, as it turns out, is 17. We know that protons and electrons carry equal but opposite charges, so to balance the net charge of chlorine back to 0, it must have 17 electrons.
If Chlorine has 17 protons and negative one charge how many electrons does it have?
Chlorine with 17 protons and a -1 charge has 18 electrons. This is because the number of electrons should equal the number of protons (in this case, 17) plus or minus the charge (in this case, -1).
Equal to the number of protons in an atom found on the periodic table?
The atomic number or the number of electrons is equal to the number of protons.
How do you find electrons in elements on the periodic table?
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
Are protons and electrons both found in the nucleus of a chlorine atom?
No, protons are found in the nucleus of a chlorine atom, while electrons are located outside the nucleus in electron shells. Chlorine has 17 protons in its nucleus, but the number of electrons is equal to the number of protons to maintain overall charge neutrality.
