Answer:
The electronegativity from order of least to highest is:
Ne, Ca, Fe, F
Explanation:
Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).
According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.
Hence, based on Pauling scale, the order of electronegativity from least to highest is:
Ne > Ca > Fe > F
Answer:
C. the boiling point of water
Explanation:
B is correct because boiling point only usually differs among the same substance when pressure changes. So say you take one solution onto a mountain top and another at sea level, the boiling point will not be the same, but here we assume they are in the same place so it won't.
A cannot be because the containers are all different shapes (and we aren't talking about like molecular shape of water from what I assume, we mean macroscopically, so that can't be).
B cannot be because we have 4 different temperatures.
D cannot be because we have 4 different temperatures, and therefore different amounts of steam will be released per minute as not all the waters have reached boiling.
The answer is electron.
The nucleus of a neutral potassium atom is "surrounded" by electron.
The neutral potassium atom contains equal number of protons and neutrons, and there are 19 electrons and 19 protons while 20 neutrons.
20 protons and 20 neutrons are there in the nucleus while 19 electrons surrounds the nucleus in different orbits .
