Answer: Option (d) is the correct answer.

Explanation:

Group 2 elements are also known as alkaline earth metals and they are rich in electrons.

For example, calcium is a group 2 element with atomic number 20 and its electronic configuration is 2, 8, 2. In order to gain stability, calcium loses to electrons and becomes Ca^{2+} ion.

Similarly, all the elements of group 2 donates electrons in order to form ionic bonds.

Hence, we can conclude that all group 2 elements have in common that they tend to form ionic bonds by losing electrons.

The correct answer would be the last option.  The property that is common to all group 2 elements is that they  tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.

Whats the structure and bonding of sodium chloride
anastassius [24]
Sodium Chloride is ordinary table salt

You have a small sodium atom with a positive charge Na+, and a larger chlorine atom with a negative charge, making it a Chloride ion, Cl-.

This ion formation has resulted from Na transferring one of its electrons to Cl. there opposite charges then attract them to each-other.

Because the electrons are transferred rather than shared, we know that the bond is Ionic, rather than covalent.

Most ionic compounds, if not all, are salts that form a crystal lattice structure, due to the opposite charges in the molecule.

Think of it like this

Na+—Cl-
Cl—-Na+
Na+—Cl-

That’s how the molecules attract and stick to each other. That would continue until you ran out of NaCl molecules.

How many types of atoms in this picture?
weqwewe [10]

Answer:

Nitrogen (N), carbon (C), hydrogen (H) and oxygen (O).

Explanation:

Hello,

Given the shown organic compound, we refer to types of atoms to the elements present in the compound, thus, we find nitrogen (N), carbon (C), hydrogen (H) and oxygen (O) that are bonded via single or double bonds in such compound.

Let's remember that compounds like that, having those elements are mainly found in biochemical substances such as proteins, a very important source of benefits for our body.

Regards.

In the balanced equation 4Fe + 3O2 = 2Fe2O3 how many atoms of iron (Fe) are reacting with every three molecules of oxygen (O2)?
Y_Kistochka [10]
This balanced equation shows us the ratios of reactants and products, so for every 3 oxygen molecules, we see that 4 iron atoms react as well. The answer is 4.
