The correct option is this: TOTAL REJECTION OF THE EARLY VERSIONS FOR MODERN IDEAS.
The modern periodic table arrangement was as a result of many contributions from many scientists, who contributed individual knowledge. The periodic table has gone through a lot of reexamination and it is always regularly updated as new scientific facts emerge. The elements in the periodic table are arranged based on the periodic occurrence of the chemical and physical properties of the elements.
Answer:
I would say a cooled
Explanation:
because yeah it's going to be cold when it travels from Antarctica but then it's going on towards Africa and yeah the water is going to get warmth but it's going to cool the land of Antarctica because it's so dry and hot and humid but the water is going to be more warmed because Antarctica the water is freezing so you're trying to ask the temperature of the water it'd be more warm if you're trying to ask kind of like the temperature of the land it would be cooled
Answer:
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^2
Explanation:
Answer:
d. IF3
Explanation:
The Octet rule posits that atoms gain, atom lose, or share electrons in order to have a full valence shell of 8 electrons. This statement occurs when atoms also combine to form molecules until they attain or share eight valence electrons either by losing or gaining eletrons.
From the given options, a valid Lewis structure that cannot be drawn without violating the octet rule is IF3
Answer:
25.0g is the mass of sulfur
Explanation:
The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.
To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:
<em>Moles O = Moles S:</em>
12.5g O * (1mol / 16g) = 0.781 moles
<em>Mass S:</em>
0.781 moles * (32g / mol) =
<h3>25.0g is the mass of sulfur</h3>
