Which statement(s) is/are correct?
(select two answers)
Excluding the transition metals, all ions in a group have the same charge.
The elements on the left side of the PT tend to form cations, and the elements on the right side tend to form anions.
The elements on the right side of the PT tend to form cations, and the elements on the left side tend to form anions.
Excluding the transition metals, all ions in a period have the same charge.
What happens to an atom when electrons are lost/removed?
(select two answers)
The atom also loses protons so that it can remain electrically neutral.
The atom has a positive charge.
The protons outnumber the electrons.
The atom has a negative charge.
The electrons outnumber the protons.
What happens to an atom when electrons are gained/added?
(select two answers)
The atom also loses protons so that it can remain electrically neutral.
The atom has a positive charge.
The protons outnumber the electrons.
The atom has a negative charge.
The electrons outnumber the protons.
Is the identity of an element changed when electrons are gained or lost?
(select two answers)
Changing the number of electrons does not change the identity of the atom; only the charge changes.
In order to change the identity of an atom, there must be a change in the number of protons in the nucleus.
Changing the number of electrons does change the identity of the atom since it converts a neutron into a proton.
In order to change the identity of an atom, there must be a change in the number of neutrons in the nucleus.
Why do most atoms have "Noble Gas Envy"?
(select two answers)
After electrons are gained/lost, the arrangement of the remaining electrons resemble noble gases.
After electrons are gained/lost, they find noble gas atoms to join.
"Noble Gas Envy" implies that other atoms want to be stable like the noble gas atoms.
"Noble Gas Envy" implies that other atoms want to be green like the noble gas atoms.
The element tin, Sn, can lose or gain four electrons. What is the charge on the tin atom if four electrons have been removed?
(select one answer)
+4
-4
+/- 4
0
Does the element silicon, Si, resemble a noble gas after four electrons have been removed?
(select one answer)
Yes, it will have the same number of electrons as the noble gas neon, Ne.
Yes, it will have the same number of electrons as the noble gas argon, Ar.
Yes, it will have the same number of electrons as the noble gas krypton, Kr
No, losing four electrons will not make it resemble the electron configuration of a noble gas.
