Zinc and Calcium
What else can I help you with?
Which element have two valence electrons?
Calcium (Ca) has two valence electrons.
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
What element has two fewer valence electrons than noble gases?
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
How many valence electrons does an element in 5A contain?
5 valence electrons.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
Which element have two valence electrons?
Calcium (Ca) has two valence electrons.
How many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
What element has 6 valence electrons?
The element with 6 valence electrons is carbon.
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
What element whose valence electrons is full with two electrons on the periodic table?
Helium
How do you know how many valence electrons does calcium have?
its in column two on the periodic table, so therefor it has two valence electrons .
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
What is the charge of valence electrons of calcium?
The charge of valence electrons in calcium is +2. This is because calcium belongs to Group 2 of the periodic table, which means it has 2 valence electrons. Valence electrons are the outermost electrons in an atom that participate in bonding.
What element has two fewer valence electrons than noble gases?
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
How many electrons does Ba has?
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
What are Valence elcetrons?
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determine the reactivity of an element. The number of valence electrons influences the element's properties and behavior in chemical reactions.
