Why can some insects walk on water

Water striders are small insects that are adapted for life on top of still water, using surface tension to their advantage so they can “walk on water.” ... The attraction between water molecules creates tension and a very delicate membrane.

Explanation:

Insects like water striders are small insects that can walk over water. Three key factors allow bugs to walk on water: surface tension, weight distribution and their long, hairy legs.

Explanation:

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.  

can you list the answers so i can answer
