The correct answer is (a) wave the fumes toward your nose with your hand. If you smell the chemicals directly, it could be harmful too your health, especially if they are strong. Also remember to <em>never </em>smell chemicals unless you are being told to do so.
In an ionic compound the atoms are linked via ionic bonds. These are formed by the transfer of electrons from one atom to the other. The atom that loses electrons gains a positive charge whereas the atom that accepts electrons gains a negative. This happens in accordance with the octet rule wherein each atom is surrounded by 8 electrons
In the given example:
The valence electron configuration of Iodine (I) = 5s²5p⁵
It needs only one electron to complete its octet.
In the given options:
K = 4s¹
C = 2s²2p²
Cl = 3s²3p⁵
P = 3s²3p³
Thus K can donate its valence electron to Iodine. As a result K, will gain a stable noble gas configuration of argon while iodine would gain an octet. This would also balance the charges as K⁺I⁻ creating a neutral molecule.
Ans: Potassium (K)

Answer:
Mass on the moon is 5.1 kg.
Explanation:
Given mass on earth = 5.1 kg
acceleration due to gravity on moon = 1.6 ms⁻².
The mass on the moon does not change because mass is the quantity of matter in the body regardless of its volume or of any forces acting on it.
Whereas the weight of the object changed.
Weight is the the force exerted on a body which is related to mass and expressed as W = mg.
W = weight of object m = mass of object and g = gravitational force
N stands for newton unit of weight.
Thus mass of the object on moon is same as on earth which is 5.1 kg.
