What is the mass number of an element that has 19 protons?
Fluorine is a non metal element. Mass number of it is 19.
If an element has 8 protons and 8 neutrons in its nucleus and 8 electrons revolving around the nucleus What is the atomic number and atomic mass of this element?
In neutral atoms (with the same number of protons and electrons), the number of protons and electrons equal the atomic number. If our atom has 9 electrons, is neutral, and therefore has 9 protons, it is element #9: Flourine, which has an atomic mass of 19: 9 protons plus 10 neutrons.
If argon is 18 then what is 19?
K - Potassium. Just look at atomic numbers on periodic table! potassium
How many neutrons does potassium have'?
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39. Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
What is the electron configuration of K 19?
Potassium is the group 1, period 4 element on the periodic table. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1. This can be shortened to [Ar] 4s1 because argon's electron configuration is 1s2 2s2 2p6 3s2 3p6.
How can you identify the number of protons?
The atom's atomic number is equal to the number of protons in its nucleus.For example, an element with 19 protons in its nucleus is Potassium (K), the 19th element on the periodic table.
What element has a greater number of protons potassium or selenium?
Selenium has 34 protons and potassium has 19. The proton number corresponds to the position of the element in the periodic table.http://www.rsc.org/periodic-table/?gclid=CjwKEAjw2MOhBRCq-Nr87_j-lDASJAAl4FNhssVbsyCT_UjwmmrpVjUngib6tHybHy88YrC1gH_1shoCZDzw_wcB
What element has 16 protons 19 neutrons and 18 electrons?
35, 16, and another number. S=Sulfur off the periodic table.
Which element has 19 protons and 1 valence electron?
Potassium has 19 total electrons and one electron in its 4th energy level.
What symbol does potassium have on the periodic table?
The element potassium has the symbol 'K' on the periodic table. Its atomic number is 19.
What element has more protons than chlorine but fewer than potassium?
Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
What will be the element name of an atom with 9 potons and 10 neutrons?
Fluorine. Number in periodic system = Number of protons
Is potassium a compound or an element?
Potassium (K) is an element. It is available on the periodic table of elements.
What does k stand for in the periodic table of elements?
In the periodic table of elements, the symbol K represents potassium. It is the 19th element on the periodic table and is an alkali metal with the atomic number 19.
Why is argon before potassium on the modern periodic table?
Argon, with an atomic number of 18, comes before potassium, which has an atomic number of 19, because elements on the periodic table are arranged in order of increasing atomic number. This ordering is based on the number of protons in the nucleus of each atom.
How many protons does potassium's nucleus have?
It has 19. If you look at the periodic table of elements potassium (k)'s atomic number is 19. An atomic number Is how many protons is in it's nucleus. So the answer is 19
How many protons does patassium have?
A potassium atom has 19 protons.An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.
