What period of prenatal development lasts the shortest?
The germinal period is the shortest period of prenatal development, lasting approximately two weeks. This period begins at fertilization when the egg is fertilized by sperm and ends when the fertilized egg attaches to the uterine wall.
What is a refactory period?
Refractory period is the period after a stimulus is given when something needs to recover in a resting state before it can respond to stimulus again. It is a term used in both physiology and psychology.
What happens to self-esteem during adolescence?
During adolescence, self-esteem can fluctuate due to the physical, emotional, and social changes happening. It can be influenced by factors such as peer acceptance, academic performance, and body image. Positive experiences and a supportive environment can help boost self-esteem during this period.
Which development marked the end of the prehistoric period and the beginning of the historic period?
The development of writing is considered to mark the end of the prehistoric period and the beginning of the historic period. Writing allowed for records of events and communication over time, leading to a more organized and structured society.
How much electricity does the brain produce in a given period of time?
The brain produces about 20 watts of electricity in a given period of time.
What happens to the atomic mass of the element moving from left to right within a period?
The Atomic Mass usually increases, but there are a few exceptions, such as tellurium to iodine.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
What is the relationship between atomic number and density within an element family?
covalent particles between the boron family share the same amount of macro particles and they end up being stable do to the fact that boron does not have a melting or freezing point and remains a liquid.
What column and row is the element Re found in?
The element rhenium (Re), atomic number 75, is in column 7 and period 6 on the periodic table.
What number is iodine on the periodic table?
Atomic number 53, column 17, and period 5.
What are terms refer to the periodic table?
Group: a vertical column Period: an horizontal row
In general the atomic radius of an atom as you move down a column in the periodic table?
Decreases. Look at the images under atomic radius, on wikipedia.
Does atomic size decrease going left to right within a period?
It decreases.
What physical trends for atomic number versus covalent radius?
As the atomic number increases within a period (row) on the periodic table, the covalent radius generally decreases due to increasing nuclear charge pulling the electrons closer to the nucleus. Within a group (column), as the atomic number increases, the covalent radius tends to increase since new electron shells are being added, leading to a larger atomic size.
How do atomic numbers and atomic masses increase in the periodic table?
Atomic numbers increase from left to right across a period on the periodic table. This is because each element in a period has one more proton in its nucleus compared to the element before it. Atomic masses generally increase from left to right as well, but there may be deviations due to isotopes or other factors. Within a group or column, atomic numbers and atomic masses increase from top to bottom as each successive element has more electrons and neutrons than the one above it.
What accompanies an increase in atomic number within a specific period?
An increase in atomic number within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
