The order is:
- Iodine (7 valence electrons)
- Carbon (4 valence electrons)
- Calcium (2 valence electrons)
- Sodium (1 valence electron)
What else can I help you with?
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
How many valence electrons are in CaO?
Calcium oxide (CaO) consists of calcium (Ca) and oxygen (O). Calcium, a group 2 element, has 2 valence electrons, while oxygen, a group 16 element, has 6 valence electrons. Therefore, in total, CaO has 2 (from Ca) + 6 (from O) = 8 valence electrons.
Which element have two valence electrons?
Calcium (Ca) has two valence electrons.
Calcium valence electrons are?
Calcium has a total of two valence electrons.
Which atom below has 4 valence electrons?
Carbon is a typical tetravalent chemical element.
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
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.
Which element have two valence electrons?
Calcium (Ca) has two valence electrons.
How many valence electron does Ca have?
Calcium's atomic number is 20. It therefore has 20 protons and 20 electrons. Since calcium is a group 2 element, 2 of those electrons are valence electrons.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
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 .
Calcium valence electrons are?
Calcium has a total of two valence electrons.
How many valence electrons have calcium?
Calcium has two valence electrons.
State the number of valence electrons in an atom of calcium?
A calcium atom has two valence electrons.
How many valence electron does calcium have?
Calcium has 2 valence electrons, like all Group 2 elements.
Which atom below has 4 valence electrons?
Carbon is a typical tetravalent chemical element.
