What elements would be most likely to form a compound bound tightly together with a covalent bond?
four hydrogen atoms and one carbon atom to form methane (CH4)
Which best explains why cations are smaller than atoms from which they are formed?
A cation has had electrons removed. So, although cations and their parent atoms have the same number of protons in the nucleus they have a different number (lower) of electrons. This means the same number of protons pulls the smaller number of electrons closer to the nucleus and so the remaining electrons are more tightly bound by the nucleus and hence the reduction in size.
Choose the element that will most easily lose an electron?
Alkaline Earths will most easily lose an electron. This is because the have a smaller alkali radii than alkali metals causing them to not be as tightly bound to the nucleus. This makes the more readily lose their electrons.
How do you account for fair and poor conductors of electricity?
The mobility of the electrons in matter. Tightly bound electrons make for poor conductors.
What 2 things do eukaryotic cells have that prokaryotic cells do not?
Eukaryotic cells have a membrane-bound nucleus but prokaryotic cells don't! The DNA in the Prokaryotic cell is in a singe loop but the DNA in the eukaryotic cell is everywhere. Prokaryotic cells don't have membrane-bound organelles.
The nucleus with the most tightly bound nucleons is?
iron
Are regions of cell membranes tightly bound together?
yes
M shell electrons are more tightly bound?
Electrons found in the K shell are more tightly bound compared to all other shells. This is because it is the innermost shell and is closest to the nucleus.
Where is the DNA stored in a cell?
In the Membrane bound nucleus
Organism whose cells each have a membrane-bound nucleus?
A cell that has a membrane-bound nucleus is called a eukaryotic cell. Prokaryotic cells do not have membrane-bound organelles.
Why broom is sturdy because its strands are tightly bound?
What kind of proverb a broom is sturdy because its strands are tightly bound
What word is the meaning of succinct?
Girded or tucked up; bound; drawn tightly together., Compressed into a narrow compass; brief; concise.
Why Halogens are not identical?
The atomic weights are different. This means more protons and neutrons in the nucleus and thus more total electrons. This in turn means the outer electrons are further away from the nucleus and not as tightly bound which cahnges the reactivity and electronegativity.
Why is Cs more electropositive than Rb?
The single outer electron is further away from the nucleus and thus is less tightly bound and thus it is energetically easier to remove that electron
What kind of Proverb is a broom is sturdy because it's strands are tightly bound?
What kind of proverb a broom is sturdy because its strands are tightly bound
When an unstable isotope gives off any kind of radioactive decay known as an alpha particle it is giving off?
It is giving off an Alpha particle. This is the nucleus of a helium atom, i.e. 2 protons and 2 neutrons (tightly bound together), without accompanying electrons.
What can kites be made of?
Anything that has very little mass and is bound together tightly. (wool cloth, silk cloth, garbage bags, etc.)
