Answer: magnesium + oxygen =magnesium oxide
Explanation: When Magnesium reacts with the molecules of oxygen , Magnesium oxide is produced.
Mg (s) + O (g) → MgO (s)
In this equation, both magnesium and oxygen are present in its elemental state.
Magnesium is present in solid form and oxygen is present in gaseous form.
The Bonding between the Magnesium and the oxygen is purely IONIC bonding as Magnesium loses its 2 valence electrons to complete its octet and oxygen gains its electrons to make its electron count 8 in the valence shell.
Answer: (B) Magnesium + oxygen =magnesium oxide
Explanation:
alkaline earth metal.
halogen.
inner transition metal.
Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, chlorine belongs to halogen family.
Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
Chlorine is a Halogen. These are all elements in Group 17 (right next to the Nobel Gases). Atomic number of chlorine is 17. Chlorine needs only one electron to completes its octet. Chlorine exist as gas.
Therefore, chlorine belongs to halogen family.
