there is amount of proton = amount of electron. and the mass = amount of proton + amount of neutron. so we take the mass - amount of pronton we will get the amount of neutron =20.8
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
The number of protons is an atom's defining characteristic. Those 17 protons are what gives chlorine the properties of chlorine. With 18 protons it would be not chlorine, but would be argon.
15 protons is a dead giveaway that we're dealing with phosphorus (it is atomic number 15). 18 electrons means it has 3 extra (18-15 = 3) electrons, each electron has a -1 charge, so we have 3 extra -1 charges... So putting it all together we get: P 3-
Protons have a +1 charge. Electrons have a -1 charge. Neutrons are neutral, therefore this atom as described will have a -4 charge.
SULFUR has 16 protons. But no neutral atom of an element can have MORE Electrons than Protons. This means that NO element can have 16 Protons and 18 Electrons.
When you're 18 most people finish college and they say they are gonna move out.
Ar 3+ . At its neutral state Argon (Ar) has 18 protons and 18 electrons. In order to have 15 electrons it has lost three electrons. Therefore Ar will have a 3+ charge.
No - O-18 has 8 protons and 10 neutrons for total in the nucleus of 18
Argon is the element with 18 protons. The number of protons of any given element is easily accessible by looking at a period table, usually in the upper portion of the squares that represent each of the elements.
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 S 2- .
That particular atom will have a positive two (+2) charge. Charged atoms are more commonly known as ions.
A chloride ion (of the isotope 35 Cl) with a charge of -1. The 17 protons tell you its chlorine and since there is one more electron than proton it has a charge.
The ion that has 17 protons and 18 electrons is a chlorine ion.This chlorine ion also has 18 neutrons.
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
The ion is K + also known as Potassium Melting Point: 63.65 Â°C (336.8 K, 146.57 Â°F) Boiling Point: 774.0 Â°C (1047.15 K, 1425.2 Â°F)
An element with 17 protons and 18 neutrons would have 17 electronsif it was neutral.
Calcium has an atomic number of 20 meaning it's composition needs 20 protons. By having 20 protons it needs 20 electrons to balance it. So a calcium ion with 18 electrons would be calcium +2.
All Chlorine atoms have 17 protons. However, ISOTOPES exist, which are atoms with varying numbers of neutrons. (A Chlorine atom with 17 neutrons would not be considered an isotope, because it has the same number of neutrons as protons) It is impossible to tell how many neutrons a particular atom… has, (unless you have some really high tech equipment to work with) so for the sake of chemistry, we sample a bunch of atoms of a given element (Chlorine, in this case) and take the average number of neutrons. We add that decimal to the number of protons that the element ALWAYS has, and end up with the average atomic number. On the periodic table, the average atomic number is listed underneath the Cl symbol as 35.45. This means that the average Cl atom has 17 protons and just over 18 neutrons (17 + 18 = 35). SO, the best answer to your question is "An isotope of Chlorine has 17 protons and 18 neutrons." **I would review the definitions for atomic number and mass number. Also look up how isotopes are written (with numbers to the left of the element's symbol). (MORE)
The ion charge is minus three. Electrons are negatively charged and there are three more of them than of the oppositely charged protons.
Only neutral elements have the same number or protons and electrons so what you have is an ion. The atomic number of 17 means the element is Chorine but the symbol would be Cl -1 because it has gained an electron.
No neutral atom can have the numbers given, because the number of electrons is not equal to the number of protons. An atom or ion of vanadium, chemical symbol V, has 23 protons, and if it also contains 28 neutrons must have the mass number of 23 + 28 = 51. This is the most common isotope of vanadium…. In the compound potassium vanadate with formula KVO 3 , vanadium is generally considered to have a formal charge of +5. corresponding to the given number of protons and electrons. Therefore, the letter V in KVO 3 could plausibly be said to satisfy all of the conditions of the problem. (MORE)
The atomic number is the same as the number of protons in an atom of the element. A periodic table or other reference shows that argon is the element with atomic number 18. The atomic mass number is the sum of the numbers of protons and neutrons, 38 in this instance. Therefore, the only actual cor…respondence to the conditions specified in the question is the isotope argon-38. (MORE)
Chlorine is the element with 17 protons, and it is a positive ion with a 1+ charge, so the symbol would be 35-Cl + . This is very unusual for chlorine, as it nearly always forms negative ions.
While "Maybe you should open a science book and find out" is a good idea and makes me laugh, it does not answer the question. The answer is Cl-.
Because that's a part of life. You Have to be 18 so u can vote, drive, etc.
Mass number is always the sum of the numbers of protons and neutrons; in this instance, 34.
It is NOT an atom but a 1+ ion of Chlorine Cl + (atomnumber 17, massnumber 17+18=35) isotope 35.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
There isn't an element, because the amount of electrons has to be equal to the amount of protons in an element.
ONLY the K + ion (not element) has 19 protons and 18 electrons. The isotopic ion with 21 neutrons must be K + -40 , the most rare potassium-ion (0.01%) out of three possibles, the other isotopes are: K + -39 (93%) and 7% is K + -41 Explanation: 39, 40 and 41 are the mass numbers of… the 3 naturally occurring potassium isotopes. Keep in mind that: 1. an element is always neutrally charged, so the number of protons (positives, + ) equals the number of electrons (negatives, - ) 2. the number of neutrons depends on the 'mass number' of the one particular isotope of that element and that the number of protons + neutrons is the mass number (MORE)
An atom's atomic number gives its number of protons. Fluorine's atomic number is 9. Thus, it has 9 protons, regardless of isotope.
Such an ion will be very, very im possible! H 17- would have 1 proton (charged +1) and 18 electrons (charged -18) with net charge 17-
Ionof Element number 19 is the potassium ion: K + Since 19(p + ) - 18(e - ) = 1 +
Well, it must be 3 - , because 18 negatively charged electrons is three more than 15 positively charged protons.
Argon (Ar)....Argon has 18 protons as shown by the periodic table...And 18+22=40, which is the atomic weight of Argon
Argon cation Ar + , atomic number 18, mass number 36 and 17 electrons. However this does not exist, argon can not easily be put in cationic ( + ) state.
The number of protons = atomic number. The element with atomic number 18 on the periodic chart is argon.
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
Only one isotope has a given number of protons andneutrons. In this case it is Argon-40
protons and electrons are equally charged except that protons are positively charged and electrons are negatively charged, as there are more protons in this example there is a positive net charge
The atomic number of am element is determined by its number of either electrons or protons, hence here, it is 18. Therefore the element must be argon which the isotope has mass number 38, as there are 18 protons and 20 neutrons.
The mass number is the sum of neutrons and protons. Thus, if there are 17 protons and 18 neutrons, the mass number is 35.
The 17 protons tells us that this element is Chlorine, since atomic number is the number of protons. The additional electron means that the chloride ion has a charge of 1 - . So the symbol for the chloride ion is Cl - .
The atomic number of oxygen is 8. So it has 8 protons. And O-18 isotope has 10 neutrons.
The Potassium 1+ ion. Potassium 1+ acts like argon a little with the number of electrons.
No, 17 O and 18 O have differing numbers of neutrons , which make them isotopes of oxygen, along with 16 O.
The isotope oxygen-18 has the mass number of 18. The atomic number of oxygen is 8, so all of its atoms, regardless of isotope, have 8 protons. In a neutral oxygen atom the number of protons equals the number of electrons, so it has 8 electrons. The number of neutrons equals the mass number minus the… atomic number, which for oxygen-18 is (18 - 8), so there are 10 neutrons. (MORE)
20 protons indicate that the particle has an atomic number of 20 and is thus, calcium Ca. Since it has two more protons than it has electrons it must have a charge of 2+. So, the symbol will be Ca 2+ .
This would be isotope 43 Ca with an oxidation state of-6, which seems unlikely since Ca has oxidation states of +2 and+1, with the former being more common. Please see the links.
