The most likely bond between element X and Iodine would be an ionic, or electrovalent, bond. Iodine has seven electrons in its outer shell, also known as the valence shell. To become perfectly stable, it needs only a single electron from another element. Hence no sharing of electron takes place (usually), which is the condition required for it to be covalent bonding. Hence it's most likely an ionic bonding/

Answer:
s an example, the ground state configuration of the sodium atom is 1s22s22p63s1, as deduced from the Aufbau principle (see below). The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s22s22p63p1 configuration, abbreviated as the 3p level.

Answer:
CaCl₂.6H₂O
Explanation:
- If we suppose that the compound has a mass of 100.0 g, it will contain 18.29 grams of Ca, 32.37 grams of Cl, and 49.34 grams of water.
- We can convert the grams of each element to moles by dividing the number of grams by the atomic mass of each element.
No. of moles of Ca = (18.29 g) / (40.0 g/mol) = 0.457 mol.
No. of moles of Cl = (32.37 g) / (35.4 g/mol) = 0.914 mol.
No. of moles of H₂O = (49.34 g) / (18.0 g/mol) = 2.74 mol.
- The no. of moles of (Ca: Cl: H₂O) is (0.457 mol: 0.914 mol: 2.74 mol).
- To obtain the ratio of the elements in the compound, we divide over the lowest no. of moles (0.475).
So the mole ratio of (Ca: Cl: H₂O) is (1: 2: 6).
So, the formula of the compound is CaCl₂.6H₂O.
