Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
The valence shell is the outermost electron shell containing electrons.
A potassium ion (K+) has 18 electrons. Potassium has 19 electrons in its neutral state, but when it loses one electron to become an ion, it has 18 electrons.
Potassium (K) can achieve eight valence electrons by losing one electron to form a stable cation with a +1 charge. In this form, it will have the same electron configuration as the nearest noble gas (argon), which has a full valence shell with eight electrons.
Potassium (K) has one valence electron.
A neutral potassium atom has 19 electrons in total and 1 valence electron.
there are 3 valence electrons in the atom of aluminum
Potassium (K) is an alkali metal whose atoms have one valence electron. The atomic number of K is 19, which means its atoms have 19 protons in their nuclei. A neutral K atom also has 19 electrons. An atom of K will lose its single valence electron to become a K+ cation. Therefore, there are 18 electrons in a K+ cation.
An electric-neutral K atom has 19 protons and 19 electrons.
Potassium (K) has 1 valence electron and Bromine (Br) has 7 valence electrons. Therefore, the total number of valence electrons in KBr is 1 (from K) + 7 (from Br) = 8 valence electrons.
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
Potassium has 19 electrons when it's neutral. It's ionic form is K+. Thus, the potassium ion has one less electron than that, or 18.
