Explain why a hydrogen atom doesn’t have a neutron in its nucleus.
Answer: Hydrogen does not contain neutron, because its nucleus is smallest in size which cannot accommodate any heavier neutron. It also makes hydrogen atom unstable in nature.
Explanation:
Each atom consists of a central nucleus and several shells that contain electrons. The outermost electrons are called valence electrons. Most atoms are stable with a configuration of eight valence electrons. This is known as the octet rule. How many valence electrons does each atom have? * 1 point
Explanation:
Not only did outermost electron determine the valence electron, but also periodic table. whatever group they fall into in periodic table each valence electrons present in a particular atom e.g K and Ca belong to group 1 and 2 respectively and k has 1 and Ca have 2 in each outermost electron

Explain how conditions in the mantle crate a conventional current
Answer:
As the warmer material rises, it also cools, eventually pushed aside by warmer rising material and sinking back toward the core. Mantle material flows slowly, like thick asphalt or mountain glaciers. While the mantle material remains solid, the heat and pressure allow convection currents to move the mantle material

Which element's atoms are most likely to touch each other without overlapping?
iron
hydrogen
carbon
radon
Answer: iron
Explanation: Metals' atoms are closely bonded in a crystal lattice. In metallic bonds, the electron cloud boundaries of atoms touch each other. Many nonmetals occur as diatomic molecules. The electron clouds of these two bonded nonmetal atoms overlap .
Hydrogen atoms are most likely to touch each other without overlapping because of their small size and simple atomic structure.
A hydrogen molecule is a particle of the synthetic component hydrogen. The electrically unbiased molecule contains a solitary emphatically charged proton and a solitary adversely charged electron bound to the core by the Coulomb force. Nuclear hydrogen is around 75% of the baryonic mass of the universe.
Hydrogen exist as diatomic particle, I.e., it can exist by attaching to another hydrogen. You realize that hydrogen has just a single electron in it's furthest and just shell. Yet, to accomplish a steady design, there should be two electrons in this shell. So two hydrogen molecules share their electrons by holding.

Which of the following is NOT a correct ordering of subshells in the periodic table?
O 2p < 35
O 3d < 4p
O 3d < 45
04s < 4p
3d < 4s is NOT a correct ordering of subshells in the periodic table because 4s is at a lower energy level than 3d.
According to the Aufbau principle, The electron configuration of an element tells how electrons of that element are arranged in thier subshells from their lowest energy state before the highest energy state.
For example, before a 2s subshell can be occupied, A 1s subshell must be filled.
The orbitals are filled in this order:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s,
For example, Na (sodium) with 11 atomic number is written as 1s2 2s2 2p6 3s1
Therefore,
2p < 3s True
3d < 4p True
3d < 4s False
4s < 4p True

Fermium-253 has a half-life of 0.334 seconds. How long will it take, in seconds, for a 96 atom sample to decay to 3 atoms?
The half life time period of decaying 96 atom sample to 3 atoms of Fermium-253 if it has a half-life of 0.334 seconds is 1.67 s.
What is half life time period?Half life time period is defined as the time interval which is required to decay the substance into half of its concentration. It is denoted by t(1/2).
As, atom decay in first half life time = 48 atoms.
Atom decay in second half life time = 24 atoms.
Atom decay in third half life time = 12 atoms.
Atom decay in fourth half life time = 6 atoms.
Atom decay in fifth half life time = 3 atoms.
So, we can see that in 5 half life time 96 atoms decay into 3 atoms.
So, time interval require to decay 96 atoms into 3 atoms is 5 × 0.334 = 1.67 s.
Thus, we concluded that the half life time period of decaying 96 atom sample to 3 atoms of Fermium-253 if it has a half-life of 0.334 seconds is 1.67 s.
