Laura takes her little brother for a walk in the park from the benches to the water fountain. Laura walks in a straight line while her brother runs in circles around her. They both take the same number of seconds to reach the water fountain. Which of these is true? [Hint: distance and speed are scalars, displacement and velocity are vectors] * 1 point Laura and her brother traveled the same distance. Laura’s brother had a greater displacement than Laura. Laura’s brother had a greater average velocity than Laura. Laura and her brother had the same average velocity.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
