Answer:
The first energy level is closest to the nucleus. The second energy level is a little farther away than the first. ... The electrons in the energy level farthest from the nucleus are called valence electrons. Atoms in the same column (group) in the periodic table have the same number of valence electrons.
Explanation:
Answer:
Muscle cell
Explanation:
An example of a specialized cell would be a muscle cell, which allows muscles to contract. A specialized cell has a specific function.
Answer:
the 2p5 should have filled up one more so it would be 2p6 ...which assuming it's not an excited electron?
Answer:
a)decrease
b)increase
c)smaller
d)smaller
Explanation:
Ionization energy decreases down the group due to increase in the atomic radius. The distance between the outermost electron and the nucleus increases hence the nuclear attraction for the outermost electrons become smaller and the ionization energy also become smaller as electrons are now easily removed from the outermost shell.
Hence the group of answer choices provided above.
Answer:
The total mass of reactants equals the total mass of products
Step-by-step explanation:
The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:
Reactants ⟶ products
Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
