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.
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 argon is 18 then what is 19?
K - Potassium. Just look at atomic numbers on periodic table! potassium
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 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.
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.
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.
Why is argon before potassium on the modern periodic table?
Because of its atomic number. The atomic number is a reference to how many protons an element has. Argons atomic number is 18, so it has 18 protons. Potassiums is 19.
What will be the element name of an atom with 9 potons and 10 neutrons?
The element with 9 protons and 10 neutrons is fluorine-19 (F-19).
Why is potassium located where it is in the periodic table?
Each element has its own specific spot on the table due to the number or protons in the atom, or atomic number. The periodic table is set up by that. K has 19 protons, therefore in the 19th spot
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.
Explain the relationship between atomic structure and the periodic table?
There are three main relationships that can be observed when linking element's structure to their position on the periodic table: * The group number represents the number of valence electrons in an atom. Example: lithium is in group 1, so it has one valence electron; calcium is in group two, so it has two electrons in its outer shell. * The horizontal period on which an atom lies equals the number of electron shells it contains. Example: lithium is in the second period, so it has two shells; calcium is in the fourth period, so it has four electron shells. * Generally speaking, as you read left to right along the table, the atomic number goes up by one.
What does K 19 and 39.098 represent on a periodic table?
K is the symbol for potassium. 19 is the number of protons and 39.098 is the mass number (Protons + Neutrons + Electrons).
What element contains 19 protons?
Potassium has nineteen protons.
