Which of the following statements are true about whether atoms tend to gain or lose electrons?

a. atoms with eight valence electrons easily lose electrons.
b. atoms with five, six, or seven valence electrons will gain electrons.
c. atoms with one, two, or three valence electrons will lose electrons.
d. atoms with four valence electrons will always lose electrons.

A. Atoms with eight valence electrons easily lose electrons.

Explanation:

When the atom is in the ground state, it is electrically neutral, since the amount of protons (positive charges) is exactly equal to the amount of electrons (negative charges). Thus, when it gains an electron, the atom gets an extra negative charge, so it is represented as follows: X-1, where "X" is the symbol of the chemical element. If two electrons were added, it gets a charge -2 and so on.

When the atom gains or loses electrons - this occurs in its valence shell, that is, in the outermost shell - its electron configuration changes.

b.

hope this : )

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
