An atom has 53 neutrons and and 46 protons in its nucleus. 45 electrons are contained in the orbitals outside the nucleus. Write the nuclear symbol
for this atom.

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.

it's 3.2 on edge, i just took the test.

∠gdh and ∠edh on edg.

answer is c
