<u>Answer:</u>
For 1: Atomic number : 79
For 2. Atomic mass : 197
For 3. Number of orbits : 6
For 4. Number of neutrons : 118
For 5. Number of electrons in n=3 : 18
For 6. Number of valence electrons : 1
<u>Explanation:</u>
- Atomic number is defined as the number of protons or electrons present in an atom. Here 79 corresponds to the Atomic Number.
- Atomic mass is defined as the Sum of neutrons and protons present in an atom. Here, 197 corresponds to the Atomic Mass.
- Atomic Mass = Number of protons + Number of neutrons
Here, Number of protons = 79
So,
- Valence electronic configuration of the atom having atomic number as 79 is :
Number of orbit corresponds the higher value of 'n' which is the principle quantum number. Here, n = 6 so, number of orbits are also 6.
- In orbit having n = 3, there are 3 sub-shells: s, p and d. The number of electrons that can be occupied in s-subshell = 2
The number of electrons that can be occupied in p-subshell = 6
The number of electrons that can be occupied in d-subshell = 10
Total number of electrons that can be occupied in orbit having n = 3 are (2 + 6 + 10) = 18 electrons.
- From the electronic configuration, it is visible that valence electrons in atom having atomic number 79 is 1.
Answer:
Increasing speed.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
In this scenario, an object moves with a positive acceleration. Thus, the object is moving with an increasing speed and as such it has acceleration in the same direction as its velocity with respect to time.
