Answer: im too young to know
Explanation:
Atom's chemical properties are determined by the number of electrons in its outermost shells.
Based on the number of electrons in the shells, it decides the reactivity of atoms.
Atoms with same number of electrons in the outer shells have similar chemical properties.
If atoms have 1,2 or 3 valence electrons they react by giving out those electrons to become stable. If atoms have 6 or 7 electrons in the outer shell they react by taking in electrons to complete its outer shell.
Answer:
Marbles placed inside a hollow sphere are used to describe protons in a nucleus.
Explanation:
The turn and voltage ratio of a transformer can be simply expressed by the equation:
Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.
Plugging in the given values, we have:
25 turns / 100 turns = Vs / 40 volts
Vs = 40 volts (25 turns/100 turns)
Vs = 10 volts
The answer is D.
