Answer:
The non metals form anions…
Explaination: Generally non-metals have 4 to 7 electrons in their outermost or valence shell.(Exception Carbon, silicon, etc. they have 4 electrons). Hence to achieve their octet (to have 8 electrons in their valence shell) they accept 1,2 or 3 electrons from other elements accordingly, thereby having -1, -2 or -3 charge on them (turning from neutral atoms to charged anions).
Extra info: non metals react with metals by forming anions and form ionic molecule generally but when non metals react with other non metals they form covalent molecule due to ‘sharing’ of electrons.
Hope it helps

Answer:
Explanation:
Stereoisomers are two or more atoms that have the same bonding order of atoms but there is a difference spatial arrangement of the atoms in space.
A plane of symmetry divides a molecule into two equal halves.
A chiral stereoisomer are not superimposed on a mirror image , Hence they do not posses a plane of symmetry.
As a result to that. these non-superimposable mirror images are said to be Enantiomers.
However, a Fischer Projection emanates from a two - dimensional figure which is used for presenting a three - dimensional organic molecules.
From the given question;
Fischer projection for an enantiomer of 2-bromo-2,3-dihydroxypropanal with the bromine oriented horizontally to the left and the hydroxide group oriented horizontally to the right.
we can sketch the way the enantiomer of 2-bromo-2,3-dihydroxypropanal can be seen like the one shown below:
CH₂OH

The objective of this question is to drawn the perspective formula of the molecule.
So , from the attached file below; we can see the perspective formula of the molecule in a well structured 3-D format.
The atomic symbol that could represent an isotope that undergoes radioactive decay to produce Pb-206 would be 238/92 U.
