1. Complete the following analogy: A chemical symbol is to an element as a chemical formula is to a(n)
2. The compound sodium sulfide consists of a ratio of two sodium ions (Na) to one sulfide
ion (S2). Write the chemical formula for this compound.
3. A molecule of sulfur dioxide consists of one sulfur atom (S) and two oxygen atoms (O).
What is the chemical formula for this compound?
4. Identify the ratio of atoms in the compound represented by the following chemical
formula: N205

i have no clue hope you find the answer

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

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.
