Does nitrogen have 7 protons?
Nitrogen is an atom that has 7 protons, 7 neutrons, and 7 electrons. The neutrons and protons are all stuck together in the middle of the atom and are called the nucleus.
Which is bigger K or K+?
These are electrons with “highest energy level”. When at neutral, the potassium ion in the form of K has an electronic configuration of: The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence, K is larger than K+.
Why is potassium K +?
The name derives from the English “potash” or “pot ashes” because it is found in caustic potash (KOH). The symbol K derives from the Latin kalium via the Arabic qali for alkali. It was first isolated by the British chemist Humphry Davy in 1807 from electrolysis of potash (KOH).

Why does nitrogen have 7 electrons?
The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. That means there are 7 electrons in a nitrogen atom.
What element has 16 protons and 18 neutrons?
sulfur
The atomic number of sulfur is 16. The ion has 18 electrons that mean sulfur carries the charge of -2.
Is K+ bigger than Br?
Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.
Is Br or Br bigger?
Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.
How many protons are in a nitrogen atom?
It has an atomic weight of 14.007 amu. Nitrogen is the seventh element on the periodic table. It has an atomic number of 7, so it also has seven protons. Because nitrogen has an atomic weight of 14.007 amu, its mass number is 14.
How to find the relative mass of a proton?
We thus get the relative mass of a proton: mn = 1.67492747 × 10−27 kg( 1 amu 1.6605390402 × 10−27 kg) m n = 1.67492747 × 10 − 27 k g ( 1 a m u 1.6605390402 × 10 − 27 k g) mn = 1.67492747 × 10−27 kg ( 1 amu 1.6605390402 × 10−27 kg) m n = 1.67492747 × 10 − 27 k g ( 1 a m u 1.6605390402 × 10 − 27 k g) We thus get the relative mass of a proton:
What is the mass of an isotope of nitrogen?
Mass numbers of typical isotopes of Nitrogen are 14; 15. Atomic mass of Nitrogen is 14.0067 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
What is the atomic radius of a nitrogen atom?
The atomic radius of Nitrogen atom is 71pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus.
