When is an atom electrically charged?
a electically charged atom is also known as a eletron
Determine the number eletron and neutrons and protons in 235U92?
Electrons: 92neutrons: 143 protons: 92.
What is a subtomic particale with a negative charge?
The electron has a negative charge. It is found in the electron cloud around the nucleus.
Explain why some elements are stable on their own while others are more stable in compounds?
its because some are naturally stable like helium, when some like hydrogen have an extra electron in their electron clouds. That's why they are unstable. When they meet with an element with one extra electron they can be stable because the first electron cloud holds 2 electrons. ex. : hydrogen - 1 electron hydrogen - 1 electron adding both together will give you a full eletron cloud. Hope this helps!
Which electrons are involved in chemical bonds?
The outer shell, known as the valence; it is a good indicator of an elements reactivity. If you look at the periodic table, elements in group I and VII are highly reactive because they form ionic bonds very easily due to the fact that they have one and seven eletrons in their outer shell respectively, making each very close to the octet which is where elements seem to be stable. Those in group I easily lose their one eletron and those in group VII easily gain one. It also occurs with the other groups to a lesser degree.
How are eletron location?
hp
An ion that has a negative change is formed when an atom?
Eletron
What is the mass of eletron?
About 9.109 x 10-31 kg.
How many valence eletron have in krypton?
Krypton has 8 valence electrons.
How many eletron does phosphorus have?
A neutral phosphorus atom has 15 electrons.
Why does AMINE group activate the benzene ring more than the hydroxyl group?
as nitrogen is less eletronegative than oxygen so the delocalisation of lone pair eletron to the benzene ring is more in case of amine compare to hydroxyl group
How is the element alike in the group and the period on the periodic table?
FOR THE SIZEthe elements on the periodic tabledecreases across the periodand increases down the groupFOR THE ELECTRON DIFFERENCEFor the first 20 elementacross the period the difference between two closes element is +1 eletron or -1 eletrondown the group the difference between two closes element is +8 eletron or -8 eletron
How many electrons will fluorine lose in forming an ion?
It will lose one eletron
What is the cloud model?
it is basically a model that shows the probability that an eletron exists in that position
Where does the eletron transport chain occur?
Inner membrane of the mitochondria and thylakoid membrane of chloroplasts.
When is an atom electrically charged?
a electically charged atom is also known as a eletron
Determine the number eletron and neutrons and protons in 235U92?
Electrons: 92neutrons: 143 protons: 92.
