How does fluorine's electronegativity compare to the electronegativigty of oxygen and chlorine?
Fluorine has the highest electronegativity among the three elements. Oxygen is the second most electronegative, while chlorine has a slightly lower electronegativity compared to both fluorine and oxygen.
Has similar properties with elements T but has lower atomic number?
flourine
Which chemical family has atoms with the fewest number of electrons?
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
Why oxygen have less ionisation enthalpy than fluorine?
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).
Where is the most reactive gas found?
Not counting the Noble Gases in the last group of the Periodic Table, the most active elements are located at the lower left and upper right. Assuming you are talking about pure, elemental gases, that would make Fluorine the most active gas.

What element has a atomic number lower than alumimum?
There are 12 such elements and they are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium and magnesium.

Element with similar properties with chlorine but has lower atomic number?
You think at fluorine (F).
Which has lower electron affinity between oxygen and fluorine?
This element is fluorine.
Has similar properties with elements T but has lower atomic number?
flourine
Which chemical family has atoms with the fewest number of electrons?
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
Which one is the most electronegative element in the periodic table?
Chlorine is most electronegative element. It is halogen.It is placed in group-17.The most electronegative element in the periodic table is Fluorine. The electronegativity of elements increase from left to right of a period. And decreases own a group.
What are the elements on the periodic table measured in?
Elements on the periodic table are arranged according to atomic number.Element with lower atomic number comes first.Atomic number plays an important role in characteristic of elements.
Why oxygen have less ionisation enthalpy than fluorine?
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).
Does a neutron have the same mass as an electron or a proton?
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
Why is fluorine the most chemically active of all elements?
Type your answer here... Fluorine is the most chemically active of all the group 7 elements because it is easiest for it to gain an extra electron in reactions. This is because it's electrons have the most energy to ionise as they are closer to the protons in the atom's nucleus and are more strongly attracted to them. Fluorine's electrons are closer to it's nucleus because it has less shells overall and a lower atomic mass. Having more shells weakens the force of attraction between the electrons and the protons. That's why group 7 elements get more reactive as you go up the group.
What has more hydrogen ions acidic or basic solutions?
A hydrogen ion is just a proton, H+. The pH of a solution depends on proton concentration, pH = -log of H+ concentration. Therefore, the greater the number of protons present in solution, the lower the pH number, and the more acidic the solution.
