If an electron is detached from an atom, the atom is converted to a positive ion called a(n):________
1 answer:
If an electron is detached from an atom, the atom is converted to a positive ion called a(n): <u>Cation</u>
Cations are positively charged ions formed when neutral atoms lose electrons. Chemical elements that are cations include:
- Alkali metals that lose an electron and form a cation with 1+ charge.
- The alkali metals of the earth, which lose 2 electrons and form 2+ cation.
- Aluminum, which loses 3 electrons to form 3+ cation.
The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

Answer:
500 Ns
Explanation:
According to the impulse theorem, the change in momentum of an object is equal to the impulse exerted on it. Mathematically:
where
is the change in momentum of the object
I is the impulse exerted, which is the product of
F, the net force exerted
, the time interval during which the force is applied
In this problem,
F = 100 N is the force applied on the wagon
is the time interval
Substituting, we find the change in momentum of the wagon:
