Each atom has protons, neutrons and electrons. # Protons have a positive charge (of +1). # Neutron have a neutral charge (of 0). # Electons have a negative charge (of -1). Atoms have protons and neutrons at the centre, and electrons travel around this centre (known as the nucleus) in shells or energy levels. Each shell has a maximum number of electrons. The atom is most stable when it's charges cancel out. Halogens are very reactive. They only need one electron to achieve an full shell (known as an octet or noble gas configuration). Now because they only need one, they can bond covalently with another atom of the same element and they share they're electrons so that they both have a full octet.
They bond covalently with another atom of the same element in order to get that extra electron and therefore achieve an octet. Diatomic molecules are molecules made only of two atoms and because this type of bond means only two atoms produce this molecule, halogens are diatomic.
What else can I help you with?
A chemical family whose members exist as reactive diatomic molecules in the gaseous phase?
The halogens are a chemical family whose members exist as reactive diatomic molecules in the gaseous phase. Examples include chlorine (Cl2) and fluorine (F2).
What family of elements most often exist as diatomic molecules?
The halogens (Group 17) are the family of elements that most often exist as diatomic molecules in their elemental form. This includes elements like chlorine (Cl2), fluorine (F2), bromine (Br2), and iodine (I2).
In what respect hydrogen is different from halogen?
Hydrogen is a nonmetal element, while halogens are a group of highly reactive nonmetal elements on the periodic table. Hydrogen forms diatomic molecules (H2), while halogens exist as diatomic molecules in their natural state (e.g. Cl2, Br2). Additionally, hydrogen is a gas at room temperature whereas halogens are typically gases or solids.
Which halogens are gases?
Fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2) are halogens that exist as gases at room temperature and pressure. At standard conditions, fluorine and chlorine are diatomic gases, while bromine is a diatomic liquid and iodine is a solid.
What family do diatomic elements belong to?
They belong to different families but HALOGENS family consists of diatomic molecular elements.
Do halogens form diatomic molecules?
Yes, halogens form diatomic molecules.
Which diatomic molecules have single bonds?
The halogens and hydrogen
Are Hydrogen Nitrogen Oxygen and the Halogens diatomic molecules?
Yes
Are all halogens diatomic molecules?
Yes, all halogens are diatomic molecules in their elemental form, meaning that they exist as pairs of atoms bonded together. Examples of halogens include fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2).

What property do halogens share?
They share many properties, but one is that they all have 7 valence electrons.
What period 3 diatomic elements will form ions with a negative 2 charge?
Only chlorine has a diatomic molecule biut any ion is 2-..
Are hydrogen and the halogens the only elements that can form diatomic molecules joined by a single covalent bond?
yes
How do we clasiffy molecular element?
Several chemical elements have diatomic molecules: halogens, hydrogen, oxygen, nitrogen.
