How many electrons surround the nucleus of an atom of potassium?
There are 19 electrons in the potassium nucleus.
Why Na is less reactive than K?
Potassium's 1 valence electron is farther away from its nucleus than sodium's 1 valence electron is from its nucleus. Potassium is one period up from sodium (well, down on the p.t.e., but up in number of energy levels), so the attraction between potassium's nucleus and outermost electron is a little less than in sodium, so that electron is more likely to go flying, which makes potassium more reactive.
What is the atomic core of potassium ion?
The nucleus is an electron, but in the outermost shell (= valence electron). The atomic number (Z) of potassium is 19. Therefore its electron distribution is 1s2 2s2 2p6 3s2 3p6 4s The valence electron is 4s, so the nucleus is 1s2 2s2 2p6 3s2 3p6. The potassium ion, K+, has lost one of its outermost electrons, so it has the same electrons as the nucleus of K.
Why does potassium have a larger atomic radius than bromine?
When looking at potassium and bromine, it would seem that with more electrons occupying more orbitals, bromine would be larger. However, in addition to those additional electrons, bromine also has additional protons. These protons in the nucleus pull on all of bromine's electrons with more strength than the nucleus of potassium, and the stronger pull offsets any size gained by adding electrons. In short, bromine's nucleus pulls harder.
What is the total number of protons in the nucleus of a potassium 42 isotope?
The atomic number of potassium is 19. This means that there are 19 protons in every potassium atom, regardless of isotope.
How many electrons surround the nucleus of an atom of potassium?
There are 19 electrons in the potassium nucleus.
How many protons are in the nucleus of a potassium atom?
19
Where are the protons in a potassium atom?
Protons in potassium are located in the necules
How many electrons orbit the nucleus of the potassium atom?
19
How many neutrons are in the nucleus of the potassium?
20 for the stable atom
Which element has19 protons in its nucleus?
Potassium - (K) Potassium's atomic number is 19, which is also the number of protons it has.
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
Lithium and potassium which is more reactive?
They both have 1 electron in their outer shell but because potassium has more shells, this electron is further from the nucleus. This means the outermost electron is less stronly pulled by the nucleus so it will break away easier therefore making potassium more reactive.
Why Na is less reactive than K?
Potassium's 1 valence electron is farther away from its nucleus than sodium's 1 valence electron is from its nucleus. Potassium is one period up from sodium (well, down on the p.t.e., but up in number of energy levels), so the attraction between potassium's nucleus and outermost electron is a little less than in sodium, so that electron is more likely to go flying, which makes potassium more reactive.
Where is most of potassium atoms mass located?
The nucleus - protons and neutrons. This applies to all atoms.
Why potassium is more reactive than sodiam?
Potassium is a bigger atom and so its valency electron is further from the nucleus. As a result of the greater distance the bond that holds the electron to the nucleus is weaker. This means that less energy is required for other substances to react with that electron.
What is the atomic core of potassium ion?
The nucleus is an electron, but in the outermost shell (= valence electron). The atomic number (Z) of potassium is 19. Therefore its electron distribution is 1s2 2s2 2p6 3s2 3p6 4s The valence electron is 4s, so the nucleus is 1s2 2s2 2p6 3s2 3p6. The potassium ion, K+, has lost one of its outermost electrons, so it has the same electrons as the nucleus of K.
