What is the element with 19 protons?
potassium So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.
What is the symbol for an ion with 18 electrons 19 protons and 19 neutrons?
What type of ion is formed with 19 protons 19 neutrons and 18 electrons? The symbol for the ion with 19 protons and 18 electrons is K+.
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 element has 19 protons neutrons?
Potassium-39 – It has 19 protons and atomic mass is 39. Hence, number of neutrons is 39 – 19 which is 20.
What is the charge of an ion with 19 protons and 18 electrons?
Answer and Explanation: The symbol for the ion with 19 protons and 18 electrons is K+. This indicates that there the ion has a positive charge of one, which is created by…
What has 19 protons and 21 neutrons and 18 electrons?
The element is NECESSARILY potassium.
What is the charge of a particle with 19 protons and 18 electrons?
There are 19 protons, i.e. Z=19 . The element is NECESSARILY potassium. There is ONE less electron than the defining nuclear charge, so we got K+ .
Which ion would contain 19 electrons?

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 is the atomic mass of an element that has 18 electrons and 20 neutrons its charge is?
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 symbol for ion with 19 protons and 18 electrons?
Answer and Explanation: The symbol for the ion with 19 protons and 18 electrons is K+.
What is Aluminium’s charge?
The charge of an aluminum ion is typically 3+. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.
What isotope has 19 protons and 21 neutrons?
Potassium-40 has 19 protons and 21 neutrons.
What is the ion symbol for 19 protons and 18 electrons?
Answer and Explanation: The symbol for the ion with 19 protons and 18 electrons is K+.
How many total electrons are in a ni2+ ion?
0:141:45How to find Protons & Electrons for the Ni, Ni2+, and Ni3+ – YouTubeYouTube
What is the symbol for the ion with 19 protons and 18 electrons?
Answer and Explanation: The symbol for the ion with 19 protons and 18 electrons is K+.
What has 18 protons and 20 neutrons?
You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element….and thus we got calcium…. ….and with 20 neutrons we got the 38Ca isotope….the which is rather short-lived….
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 name of ba2+?

How is Al2O3 formed?
How is aluminium oxide produced? This process starts by drying crushed and washed bauxite, usually containing 30–55% Al2O3 (4). The bauxite is dissolved in caustic soda to form a slurry, heated to temperatures of about 230–520 °F (110–270 °C).
What isotope has 19 protons 21 neutrons and 18 electrons?
The element is NECESSARILY potassium.
How many protons and electrons does Ni2+ have?
But in Ni2+ there is a shortage of two electrons but the protons are reminded the same so the charge over Ni2+ is +2 for two extra protons cause the electrons are 26 but the number of protons is still 28.
What does Ni2+ mean?
