Answer:
6
Explanation:
The maximum number of electrons in the orbitals of sub-levels are given as:
for s-sublevel we have two electrons and one orbital
p-sublevel we have six electrons and three orbitals
d-sublevel we have ten electrons and five orbitals
f- sublevel we have fourteen electrons and seven orbitals
The second energy level is represented by the p-sub-level and it will accommodate 6 electrons.
Answer: A and D
Explanation: isotopes must have same atomic number but different mass number due to the difference in their Neutron number
all of the above.
The properties of water are:
1) polar molecules
2) regulates temperature
3) universal solvent
4) high surface tension
5) can exist in all three stages of matter
Answer:
protons=1
electrons=1
neutrons=0
Explanation:
protons and electrons are equal in their natural state when it goes under any reaction the protons of that element remain the same but the number of the element changes.
