Answer:
is a way of presenting information about the chemical proportions of atoms
Explanation:
Answer:
100N
Explanation:
Given parameters:
Mass of the bowling ball = 20kg
Acceleration = 5m/s²
Unknown:
Amount of force applied = ?
Solution:
To solve this problem, we apply newton's second law of motion.
Force = mass x acceleration
Now insert the parameters and solve;
Force = 20 x 5 = 100N
Answer: Option (3) is the correct answer.
Explanation:
When there is a negative charge on an atom then we add the charge with the number of electrons. Whereas when there is a positive charge on an atom then we subtract the charge from the number of electrons.
Atomic number of chlorine is 17. So, number of electrons present in
is 17 + 1 = 18 electrons.
Atomic number of cobalt is 27. So, number of electrons present in
is 27 - 4 = 23 electrons.
Atomic number of iron is 26. So, number of electrons present in
is 26 - 2 = 24 electrons.
Atomic number of vanadium is 23. So, number of electrons present in V is 23 electrons.
Atomic number of scandium is 21. So, number of electrons present in
is 21 + 2 = 23 electrons.
Thus, we can conclude that out of the given species,
has the greatest number of electrons.
Mercury-199 is composed of 80 protons, 119 neutrons, and 80 electrons.
D) It is unlikely that a specific cause can be determined, but the treatment would likely be the same in either case
