What type of bonds will calcium form?
Calcium has 20 electrons with 2 in its outer valence shell. When Ca2+ (a metal) bonds, it donates the 2 free electrons to a nonmetal forming an ionic bond. For example : Ca2+ + Cl2- = CaCl where calcium the cation donated 2 electrons and chlorine the anion accepted 2 electrons.
Is nitric oxide dative or 'normal' covalent bond?
Nitric oxide has a dative (coordinate) covalent bond. The N has donated both electrons and the O has also donated 2 electrons to make the N=O.
Are the electrons in a coordinate bond donated by both the bonded atoms?
No - one atom provides both electrons for the covalent bond. eg when ammonia (NH3) forms an ammonium ion, the nitrogen in ammonia provides 2 unbonded valence electrons. These form the covalent bond between the hydrogen ion (H+) and the nitrogen which becomes an ammonium ion - NH4+
What happens to the valence electrons of magnesium oxide?
In magnesium oxide, magnesium transfers its 2 valence electrons to oxygen, resulting in magnesium becoming a 2+ cation and oxygen becoming a 2- anion. This transfer forms an ionic bond between the two elements, creating a stable compound.
What happens to the atom that causes a neutral object to become charged?
When an atom loses or gains electrons, it becomes ionized and can create a charged object when it interacts with other atoms. If an atom loses electrons, it becomes positively charged, and if it gains electrons, it becomes negatively charged. This imbalance of electrons between atoms creates an electric charge on the object.
When an atom forms a bond what are the 3 things that its electrons can do?
The electrons can be shared equally (covalent bond). The electrons can be shared but one atom provides those electrons and the other provides none (dative or coordinate covalent bond). The electrons can be donated by one and accepted by the other atom (ionic bond).
Which bond forms by sharing electrons in the outermost shell?
The sharing of electrons between atoms forms a covalent bond. If electrons are donated from one atom to another to form a bond this would be an ionic bond.
What type of bonds will calcium form?
Calcium has 20 electrons with 2 in its outer valence shell. When Ca2+ (a metal) bonds, it donates the 2 free electrons to a nonmetal forming an ionic bond. For example : Ca2+ + Cl2- = CaCl where calcium the cation donated 2 electrons and chlorine the anion accepted 2 electrons.
What are donated or shared when two atoms form a bond?
When two atoms form a bond, electrons are donated or shared. In an ionic bond, one atom donates electrons to the other, while in a covalent bond, electrons are shared between the atoms.
Which group donated two electrons when bonding?
group 2
What element has 12 protons 14 neutrons 10 electrons?
Magnesium2+ because it donated 2 electrons
Why is O-negative called the universal donor?
It can be donated to any person, and it is universally accepted.
Is nitric oxide dative or 'normal' covalent bond?
Nitric oxide has a dative (coordinate) covalent bond. The N has donated both electrons and the O has also donated 2 electrons to make the N=O.

What is meant by the oxidation number of an elemnet?
The oxidation number implies that how many electrons that a particular element has partially/fully accepted/donated. The oxidation number for any neutral atom is 0. The oxidation number of an atom is equal to its overall charge.
What types of donated goods are accepted by the charity organization?
The charity organization accepts various donated goods such as clothing, household items, furniture, and non-perishable food items.
When atoms share electrons what forms?
A covalent bond forms when atoms share electrons.
