16. Define atomic properties or periodic properties? How these properties vary ​

Answer»

hey mate here is your answerExplanation:Periodic Trends of Elemental PropertiesThe elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.Atomic RadiusWe can never determine the atomic radius of an atom because there is never a zero probability of FINDING an electron, and thus never a distinct boundary to the atom. All that we can measure is the distance between two nuclei (INTERNUCLEAR distance). A covalent radius is one-half the distance between the nuclei of two identical atoms. An ionic radius is one-half the distance between the nuclei of two ions in an ionic bond. The distance must be apportioned for the smaller cation and larger ANION. A metallic radius is one-half the distance between the nuclei of two adjacent atoms in a crystalline structure. The noble gases are left out of the trends in atomic radii because there is great DEBATE over the experimental values of their atomic radii. The SI units for measuring atomic radii are the nanometer (nm) and the picometer (pm). 1 nm = 1 X 10-9 m; 1 pm = 1 X 10-12m.Electron AffinityElectron affinity (E.A.) is the energy change that occurs when an electron is added to a gaseous atom. Electron affinity can further be defined as the enthalpy change that results from the addition of an electron to a gaseous atom. It can be EITHER positive or negative value. The greater the negative value, the more stable the anion is.

a body possesses an initial velocity of 5 m/s and moves with a uniform acceleration of 2 ms-2. calculate the distance moved by the body in 4s.​

Answer»

ion :Given :▪ Initial velocity of BODY = 5mps▪ Acceleration of body = 2m/s^2▪ TIME INTERVAL = 4sTo Find :▪ DISTANCE covered by body in the given interval.Concept :✒ Here acceleration is CONSTANT throughout the whole journey so we can apply equation of kinematics directly.✒ Third equation of kinematics is given by☞ S = ut + (1/2)at^2S denotes distanceu denotes initial velocitya denotes accelerationt denotes time intervalCalculation :→ S = (5×4) + (1/2)×2×(4)^2→ S = 20 + 16→ S = 36m

give an example of each when : (1) displacement of the body is equal to distance travelled by the body (2) displacement of the body is less than distance travelled by the body (3) displacement of the body is zero but distance travelled by the body is not zero​

Answer»

Displacement is the shortest STRAIGHT LINE distance between INITIAL and final position.Hence if a body travels along a random path to return to the point of start, the body has traveled finite distance, HOWEVER the displacement of it is exactly zero.Hence correct answer is option C.plz follow me
