Explanation:
The nucleus is positively charged because the proton is positive and a neutron is neutral. An electron has a negative charge.
Answer:
a. Are potentially dangerous and should not be worn.
Answer: The statement is false
Explanation:
Electrons occupy a region in atoms known as orbitals or subs hell. These orbitals include
I) S-orbital: it can occupy a maximum of two electrons
II) P-orbital: It occupies a maximum of six electrons
III) D-orbital: it occupies a maximum of ten electrons
F and G-orbitals as examples of other orbitals present.
A good illustration of the 6 electrons occupied by the P-subshell is seen in Sodium (Na) with atomic number of 11
Na = 1s2, 2S2 2p6, 3s1
Note: extra electrons are transferred to the next orbital
Explanation:
Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel.
Answer:
Explanation:
Once the steady-state phase is reached, the equilibrium concentration of the pool of unassembled subunits is called the critical concentration (Cc). This parameter is a measure of the ability of a solution of G-actin to polymerize. Under typical in vitro conditions, the Cc of G-actin is 0.1 μM.
