The element that has four total electrons in its outer P orbitals is
Sulphur (s) (answer D)
Sulphur is in group 16 and period 3 in the periodic table therefore Sulphur is in atomic number 16.
Sulphur (S) electronic configuration is 1S2 2S2 2P6 3S2 3P4 or [Ne] 3S2 3P4 therefore the 3P4 subshell of sulphur has only 4 electrons.
O High temperatures and location in high latitudes
O Moderate temperatures and location in mid to high latitudes
O Warmer temperatures and location around the equator
Answer: D
Explanation:
Answer: High temperatures and location in high latitudes
Explanation:
Given:
8.32 J of heat
from 23.2 degrees C to 30.5 degrees C
heat capacity of aluminum is 0.90 J/g-K
Required:
m in grams
Solution:
H = mCpT
(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K
m = 1.27g
b) the number of electrons in the outermost electron shell.
c) the attraction of an atom for the electrons in a covalent bond.
d) the repulsion of electrons in one atom for electrons in another atom.
Answer:
c) the attraction of an atom for the electrons in a covalent bond.
Explanation:
Electronegativity, symbol χ, is a chemical property describing an atom's ability of to attract a shared pair of electrons to itself. It is influenced by the atomic number of the atom and the distance between the valence electrons and the charged nucleus. As the electronegativity number of atoms increases, the more the atom attracts electrons towards itself.
Electronegativity is the attraction of an atom for electrons in a covalent bond. It determines how strongly an atom pulls shared electrons towards itself in a molecule.
option c is correct
Electronegativity is the attraction of an atom for the electrons in a covalent bond. It is a measure of how strongly an atom pulls shared electrons towards itself when it forms a covalent bond with another atom.
For example, in a molecule of HCl, chlorine is more electronegative than hydrogen, so the chlorine atom pulls the shared electron pair towards itself, resulting in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom.
Electronegativity increases as you move across a row or period in the periodic table from left to right and decreases as you move down a column or group.

vessel in which it is kept.
(b)A gas exerts pressure on the
walls of the container
(c) A wooden table should be
called a solid
(d) We can easily move our hand
in air but to do the same
through a solid block of wood we need a karate
expert
we need a karate expert.
Answer:
A.A gas exerts pressure on the walls of the container. Reason: They have high kinetic energy and negligible force of attraction to move constantly moving with high speed in all directions. ... These collisions of the gas particles with the container walls exert pressure on the walls of the container.
B A gas exerts pressure on the walls of the container due to imapact of its gas molecules with hight velocity .
C.A wooden table should be called a solid. Reason: It has a definite shape and volume. It is very rigid and cannot be compressed, i.e., it has a solid characteristic.
D.We can easily move our hand in air but to do the same through a solid block of wood we need a karate expert. It is because the molecules of air has less force of attraction between them and a very small external force can separate them and pass through it.
