Answer:
F, Fluorine
Explanation:
Na^+ and Mg^2+ have both lost enough electrons to bring their electron shells to that of Neon, Ne. (1s^2, 2s^2, 2p^6)
O^2- gained 2 electrons to also conform to neon's electron configuration.
F still retains its 1s^2, 2s^2, 2p^5 configuration, which would result in a slightly smaller radius as the 2p^5 electrons can pack slightly closer to the nucleus before being repelled by the negative charge of their neighboring electrons.
Poison ivy is an invasive plant species that will invade an environment and take up the nutrients in the soil and rapidly multiply.
Many times the mocking jay will invade the territory of other birds and use its mimicry to lure in birds and make them leave the area, mocking birds are extremely territorial and will use other birds nests
Potassium bromide found it on google
From ideal gas equation that is pv =nRt
n=number of moles which can be written as the ratio between the weight of a gas that is mass and its molecular mass n=m/Mm
pv=(m/Mm)RT
density is=mass per unit volume
P=m/v by arranging the equation we get
R =0.082atm/mol/k
Mm=pRT/P=[(1.10 x10^-6 x1000g/l) xo.082 atm/mol/k x(80+273] /(1.00 x10^-3) =31.84 to the nearest ten is 32
hence the gas is oxygen
