What is the chemical symbol for element with charge of 18?
There is no element with a "charge of 18". Charges are determined by electrons, so for an atom to have a charge of ±18, it would have to lose or gain 18 electrons - something an atom wouldn't do. Perhaps you mean atomic number of 18, which would be argon or Ar.
What is the element with charge if needed with 23 protons 28 neutrons and 18 electrons with a net charge of 3 plus?
No element or ion as stated can exist, because if it contains 23 protons and only 18 electrons, its net charge must be 23 - 18 = 5 plus, not 3 plus.
Why does CI have 18 electrons when its ion is -1 charge?
because chlorine has 17 protons contributing to a +17 charge, 18 electrons have a -18 charge, 17-18 = -1 which is the overall charge of the ion
What has 19 protons and 18 electrons?
Ionof Element number 19 is the potassium ion: K+Since 19(p+) - 18(e-) = 1+
How may electrons does a phosphide ion have?
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
If an atom has 15 protons 14 neutrons and 18 electrons what is the atoms electrical charge?
'-3' It is not an atom, when it is a charged species, but an ION. 15 protons (15+) 18 electrons (18-) Hence +15 - 18 = -3 The charge. By the numbers given , this is the element Phosphorus. , which can exhibit a 'P^(-3) ion.
How many unpaired electrons does phosphorus with the charge of negative three have?
18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
Is argon the only element with 18 electrons?
Yes. Argon is the only neutral element with 18 electrons. However, there can be other ions that can be isoelectronic (having same number of electrons) with argon. Cations such as K+, Ca2+ or Sc3+ have 18 electrons. Anions such as Cl-, S2- or P3- have 18 electrons.
How many electrons are in Ar- 18.?
Argon is a non metal element. There are 18 electrons in a single atom.
Ion symbol for 16 protons and 18 electrons?
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
What is the maximum of valence electrons an element may have?
18
What are the total number of electrons in the element argon?
18
