Answer:
Atom X will accept electrons from atom Y
Explanation:
The outermost shell of an atom is full when it contains 8 valence electrons (except for the first shell, which only contains 2 electrons). Therefore, any atom tends to accept electrons if it's very close to complete the shell with 8 electrons, or to donate electrons if it has only a few electrons in its outest shell.
In this case, we have:
- Atom X: 6 valence electrons --> it tends to accept electrons, since it needs only 2 of them to complete the shell
- Atom Y: 2 valence electrons --> it tends to donate electrons, so it has its outermost shell completed also
- Atom Z: 8 valence electrons --> it has no tendency in donate/accept electrons, since its outermost shell is already full
Therefore, atom Y will donate its 2 valence electrons to atom X, so that both of them have their outermost shell completed.
Answer:
Atom X will accept electrons from atom Y

The six forms of energy are chemical, thermal, nuclear, electrical, mechanical, and light energy. Each has different characteristics and uses, such as chemical energy being stored in potential changes or light energy being visible to the human eye.
Energy exists in many forms. Here are six common forms of energy:
#SPJ6
t or f
Answer:
the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
Answer:
t
Explanation:
a) a metal and a nonmetal will form a covalent bond; two nonmetals will form an ionic
bond
b) a metal and a nonmetal will form an ionic bond; two nonmetals will form a covalent
bond
c) a metalloid and a metal will form a covalent bond; two nonmetals will form an ionic
bond
Answer:
c

The answer would be three days a week
Bone-strengthening activity is key to ensuring that bones remain healthy to maintain an individual's lifestyle. The physical activity to strengthen bone may be brisk walking, exercises that include weights, or gymnastics to lift a few. The purpose of these activities are to observed to contribute to an increase in the bone mineral density of adolescents and children. Several studies have established that about 150 minutes a week for adults, or 3 days a week (60 minutes a day) for the youth should be devoted to bone strengthening physical activity to ensure good health of the body.
Hope this helps!
Answer:
three or more days a week

Answer:
Amplitud = 2 m
wavelength = 35 m
Explanation:
The waves are described by an equation of the form
Y = A sin (kx -wt)
With k = 2 π/λ
With A is the amplitude of the wave, λ the wavelength and w the velocity
If we analyze the reporter's data, the maximum height of the value from zero to the highest, which corresponds to the amplitude of the wave
The other value 35 m between each wave corresponds to the distance between the ridges that is equivalent to the wavelength
