The number of electron shells is higher.
Because they have many electron shells.
The atoms in an iron are arranged in way were they are not able to slide, there are bigger and smaller atoms. This makes the iron hard.
Nuclear radius increases as you go down and to the left on the periodic table due to effective nuclear charge. Bassicaly, it means that sheilding of electrons by larger atoms having more things in the way that blocks the ability of the nucleus to pull on the electrons, thus the electrons are able to be further from the nucleus and have a larger radius.
faster atoms have more kinetic energy than slower atoms do.
Inductive effect is effective if the group is one to three atoms away. It decreases as the distance from the group increases. Resonance effect can be felt, irrespective of the distance, as long as there is conjugation.
The bigger the atom, the larger the number of electrons between the outermost energy level and the positively charged nucleus. As a result, the attraction between the electrons in the outermost energy level and the nucleus are slightly weaker, and so, the larger the atom, the greater the sheilding effect.
Because they have many electron shells.
The proteins molecules are bigger.
Bigger cc = bigger motor = more power. But also heavier bike.
because it has more electrons
If mass is constant, density goes down as volume, or quantity, goes up. In other words, if there is more of something (or it is bigger in size), and it has the same amount of matter, then it is less dense. This is because the atoms/molecules are spread out more.
The bigger the object is the more mass it has.
bigger clouds contain more rain
When you add salt to soap it will make more bubbles. not bigger bubbles but more bubbles.
A molecule is two or more atoms which have been chemically bonded and a cell is made up of atoms so technically a molecule could be bigger than a cell but in reality most cells are bigger than molecules seeing as they are made up of them
Depends. Molecules are bigger than atoms, because they are made of atoms, a molecule can also be a compound, but compounds are more or less made of more molecules, so yes, they are bigger, you should specify the meaning of the word compound. some molecules are bigger then small componds, and anything really can be a compound
It's because atoms of oxygen join atoms of mercury, forming new chemical -- mercury oxide HgO. Since it consists of two elements, its weight will be bigger.
