What is the formula of calcium fluoride?
The reason it becomes stable is because Ca has 2 valence electrons that it wants to get rid of to become stable. F has 7 valence electrons and wants 1 more to become stable. So, TWO F atoms each take 1 of the 2 electrons from Ca. They form an ionic bond as Ca^2+ and 2F^- to make CaF2.
If 2 electrons where added to oxygen atom what would be the charge?
All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions. Gaining electrons- If atoms gain electrons then they are getting negatively charged particles making them have a negative charge. Losing electrons- If atoms lose electrons then they are losing a negative charge and they become a positively charged ion. Oxygen- Oxygen will have a negative charge before a positive charge because it needs only two electrons to have a stable valence level. For example, Oxygen will take the electrons from two Hydrogen atoms and make H20.
If a neutral atom of sodium has 11 protons how many electrons does it have?
An element with 11 protons will have atomic number 11, or sodium. If the element has 11 neutrons, then it has an atomic mass of 11+11 = 22. Therefore, the isotope Sodium-22 has 11 protons, neutrons, and electrons.
What two elements make up calcium oxide CaO?
Calcium (Ca) and Oxygen (O) are the two elements that make up calcium oxide.
How many protons and electrons are in an atom in calcium?
Calcium's atomic number is 20. That means that it has 20 protons. To make it neutral then, an atom of calcium must also have 20 electrons.
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
How do electrons an portons make a neutral charge an neutron result in a neutral charged atom?
An atom that has an equal number of protons and electrons will be neutral and have no charge.
If a neutral atom has 8 protons it must have how many electrons?
The atom must have 8 electrons to make it have a neutral charge
Why might a calcium atom want to lose the two electrons in its outer orbital?
Having just 18 electrons make Calcium nobel.
How do atoms remain neutral?
Atoms are neutral as long as they contain the same number of protons as electrons. If there are more electrons than protons, the atom has a negative charge. If there are less electrons than protons, the atom has a positive charge.
What make an atom an electrically neutral entity?
Neutrons are neutral charged, protons are positively charged and electrons are negatively charged. So since there are same number of protons and electrons, the atom becomes neutral charged/ electrically neutral entity. Simple as that!
What elements calcium carbonate make up?
Protons, neutrons, and electrons , okay?
How would Ca and Cl would make an ionic compound?
Calcium would form Ca2+ and chlorine would form Cl-. The ionic compound would be CaCl2 to ensure a neutral charge for the whole compound.
What three elements make up calcium carbonate?
Protons, neutrons, and electrons , okay?
Is an atom postively charged negatively charged or neutral?
The overall charge of the atom is neutral. The nucleus contains neutrons (neutral) and protons (positive) making it positive. There are electrons (negative) outside the nucleus, so the positive nucleus and the negative electrons make the overall charge neutral.
How many valence electrons are transferred to make calcium iodide?
It takes only one valence electron to form the calcium iodide compound.
