Answer:
Length = 393pm, Density = 21.3 g/cm^3.
Explanation:
From the question above, we have the following parameters or data which is going to aid in solving the above Question.
=> The radius of a platinum atom = 139 pm.
Therefore, the length can be calculated by making use of the formula given below:
Length = 2 √( 2r) = 2 × √ (2 × 139 × 10^-12m ) = 393 × 10^-10 m = 393pm.
The density can be calculated by making use of the chemical formula given below:
Density = mass ÷ volume = (195.064/ 6.02 × 10^23) ÷ (3.93 × 10^-10/ 10^-2) = 21.3 g/cm^3.
Answer:
B. HCN
Explanation:
PCN stands for Parent Country National. A PCN is an individual who is working in the country other than his or her native or origin country.
HCN stands for Host Country National. A HCN is the employee of the organization who is a citizen of the country where the foreign subsidiary is been located.
TCN stands for Third Country National. A TCN is an individual of other nation who is hired by a government who represents neither his host country or the government.
Hence in the context, a person who returns to his native country and works at an MNE which have its headquarter in the country where the individual studied is termed as a Host Country National or HCN.
Thus the correct option is (B).
Each orbit surrounding an atom is allowed A LIMITED NUMBER OF ELECTRONS.
The number of orbit that an atom has is determined by its atomic number, the higher the atomic number the higher the number of orbit in the atom and each orbit has different energy level. Each orbit can only take fixed number of electron. The first shell can only take two electrons while the subsequent shells can only take eight electrons. When an orbit has taken the highest number of electron possible, the remaining electrons are moved to the next shell.
