The substance nitrogen has the following properties: normal melting point: 63.20 K normal boiling point: 77.40 K triple point: 0.127 atm, 63.10 K critical point: 33.5 atm, 126 K At temperatures above 126 K and pressures above 33.5 atm, N2 is a . N2 does not exist as a liquid at pressures below atm. N2 is a at 1.35 atm and 55.8 K. N2 is a at 0.127 atm and 84.7 K. N2 is a at 1.00 atm and 70.4 K.

the objects have the same charge is correct.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
