How many valence electrons do alkali earth metals have?
ALKALI METAL OF FIRST GROP HAS 1 8ALENCE ELECTRON LIKE Na,K ETC. AND 2ND GROP ELEMENT HAS 2 LIKE Ca,Mg etc
Number of valence electrons for k?
The valence shell is the outermost electron shell containing electrons.
How can the atom K obtain eight valence electrons?
Need help understanding how the K atom could obtain eight outer shell electrons?
How many electrons are in K?
A neutral potassium atom has 19 electrons in total and 1 valence electron.
How many electrons will be in the valence shell of an aluminum atom?
there are 3 valence electrons in the atom of aluminum
How many electrons are contained in an ion formed from an atom of K?
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.
How many protons and electrons does K?
An electric-neutral K atom has 19 protons and 19 electrons.
How many valence electrons does silica have?
4
How many valance electrons does SiS2 have?
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
What electrons are in an electron dot diagram?
they are the electrons in the outer shell of the atom(valence electrons)
How many valence electron are in a potassium ion?
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.
What is the number of valence electrons for Li and K?
Both lithium and potassium have one valence electron
Why do atoms with a low electronegativity like lithium have a weak attractive force for electrons?
they have few valence electrons and aren't close to having eight valence electrons
How many valence electrons are found in alkali metals Li Na K Rb Cs and Fr?
1
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
