When ions or atoms are bound together. There is a covalent bond, ionic bond or a metallic bond
Answer: Oxygen, Beryllium, Lithium, & Fluorine
Explanation:
theoretically it might not be the answer be
Answer : The ground-state electronic configuration of oxide ion is,
Explanation :
Electronic configuration : It is defined as the distribution of electrons of atom in an atomic orbital.
<u>Oxygen</u>
The total number electrons in oxygen = 6
The electronic configuration of oxygen is,
<u>Oxide ion</u>
The total number electrons in oxide ion, = 6 + 2 = 8
The charge on O is (-2). So, we are adding 2 electrons.
The electronic configuration of oxide ion is,
The balanced equation would be:
2K+ MgBr2——> 2KBr+ Mg
So we’d need 25.6(12.8*2) moles of potassium.
Answer: a. The elements iron in the nail and oxygen from the air combine to form the compound rust.
Iron, Fe: is an element
Oxygen, O: is an element
Rust, Fe3O4: this formula identifies the product as a compound
