Hi Anyone wanna talk please

Sure, some people WANT to talk; but in some cases of injury, or birth defects causes them to not being able to talk AT ALL. So they have to write/type everything down to say something, or in some cases...people just want to be in solitude, weather they are depressed, or just wants some peace and quiet to clear their heads. some people don't want to talk to others because they are told not too, are shy, antisocial, bipolar(hate others and or self),getting bullied, doesn't trust others, or was even taught not to talk to others because there are severe consequences. But some people are just nervous, or have had so much trauma, that they have lost their sense of speech. but in my opinion, yes i'd love to talk with someone.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
