What are the total numbers of valence electrons in KBr?
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.
What is valency of an element having atomic number 20?
H, Li, Na, K = 1valence electrons Be, Mg, Ca = 2 valence electrons B, Al = 3 valence electrons C, Si = 4 valence electrons N, P = 5 valence electrons O, S = 6 valence electrons F, Cl = 7 valence electrons He, Ne. Ar = 0 because they are noble gases and all their electron shells are full
What electrons are in an electron dot diagram?
they are the electrons in the outer shell of the atom(valence electrons)
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.
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
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 are the total numbers of valence electrons in KBr?
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.

How many valence electron do Li and K have?
They each have 1.
What electrons are in an electron dot diagram?
they are the electrons in the outer shell of the atom(valence electrons)
Number of valence electrons for k?
The valence shell is the outermost electron shell containing electrons.
Which two element have the same number of valence electrons?
Elements in the same group of the periodic table have the same number of valence electrons. For example, both sodium (Na) and potassium (K) are in Group 1 and each has one valence electron. Similarly, carbon (C) and silicon (Si) are in Group 14, each having four valence electrons.
When K is neutral how many valence electrons does it have?
Potassium atom has 1 valence electron
How many valence electrons are found in alkali metals Li Na K Rb Cs and Fr?
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.
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.
