What is an ionic symbol?
When writing the symbol for an ion, the one- or two-letter element symbol is written first, followed by a superscript. The superscript has the number of charges on the ion followed by a + (for positive ions or cations) or – (for negative ions or anions). Neutral atoms have a charge of zero, so no superscript is given.

What ion has 18 electrons 19 protons and 20 neutrons?
The element is NECESSARILY potassium.
What is the symbol for an ion with 18 electrons and 19 protons is it a cation or an anion?
The symbol for the ion with 19 protons and 18 electrons is K+.
What is the symbol for the element which has 19 protons and 21 neutrons?
Potassium-40 – It has 19 protons and atomic mass is 40. Hence, number of neutrons is 40 – 19 which is 21.
What is the atomic mass number of an element that has 19 protons 19 electrons and 20 neutrons?
Hence, number of neutrons is 39 – 19 which is 20. Potassium-40 – It has 19 protons and atomic mass is 40.
What is the mass number of an element that has 18 protons 18 electrons and 19 neutrons?
Because the atomic number of an atom is same as the proton number of the atoms which means the atomic mass of the atom equal to 18. C) Correct. Because the mass number of an atom is the sum of proton number and neutron number of the atom. So, 18 + 20 = 38.
What is the electronic configuration of 19?
The electronic configuration of the element with Atomic number 19 is 2,8,8,1 or 1s22s22p63s23p64s1 or (Ar)4s1.

What is the ion symbol for an atom with 20 protons and 18 electrons?
Ca2+ Ca2+ represents an ion with 20 protons and 18 electrons.
What particle has 19 protons 22 neutrons and 18 electrons?
The element is NECESSARILY potassium.
What refers to species with 18 electrons 19 protons and 20 neutrons?
The correct option is. Potassium K+ Because the particle P has 19 protons, this means that its atomic number is 19 and hence it is a potassium particle.
What is the charge of an ion that has 20 protons and 18 electrons?
For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge.
What is the charge of 19 protons 20 neutrons and 19 electrons?
What kind of ion is formed by P ? So it will loose an electron to complete the octet and form ion having +1 charge. The element P is Potassium (K).
What will be the mass number of an atom that has 19 protons 19 electrons and 19 neutrons?
As we know that mass number is the total number of nucleons present in the nucleus of the atom of the element. So mass number is sum of neutons and protons i.e 19+20=39. Hence mass number is 39.
What is the mass number of an electron that has 18 protons 18 electrons and 19 neutrons?
Because the atomic number of an atom is same as the proton number of the atoms which means the atomic mass of the atom equal to 18. C) Correct. Because the mass number of an atom is the sum of proton number and neutron number of the atom. So, 18 + 20 = 38.
How do you find ions?
To find the ionic charge of an element you'll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative. But you need to know the specific ionic charge elments.
