An atom of sodium-23 (atomic number = 11) has a positive charge of +1. Given this information, how manyelectrons does it have? How many protons and neutrons does this atom have?
Answers
An atom of sodium-23 (atomic number = 11) with a positive charge of +1 has total number of 10 electron and this atom has 11 protons and 12 neutron.
What is atom?
Protons, neutrons, and electrons make up an atom, with hydrogen being the sole exception since it lacks neutrons.
- Every atom has a nucleus, which is surrounded by one or more electrons.
- Protons and neutrons, together known as nucleons, normally make up the same number of the nucleus.
- Neutrons are neutral, protons are positively charged, and electrons are negatively charged.
Given: An atom of sodium-23 (atomic number = 11) has a positive charge of +1.
So, total number of electrons it have = 11 -1 = 10.
total number of proton it have = 11.
total number of neutron it have = 23 -11 = 12.

Answer:
The baseball will accelerate.
Explanation:
According to Newton's second law,
The force is the product of the mass and acceleration of the object.
In mathematically term
Where, m = mass
a = acceleration
If we hit a baseball with a bat it will accelerate by the applied force.
Hence, The baseball will accelerate.

That depends on what its speed was at the beginning of 5 seconds,
and on what exactly happened to it.
If it got pushed off of the window sill and fell to the ground below,
then the answer would depend on how high the window sill is.
If the flower pot kept falling for the whole 5 seconds, then its speed
would be 49 meters per second at the end of the 5 seconds. That's
because here on Earth, gravity increases the speed of falling things
by 9.8 meters per second for every second they fall.
Naturally, this answer is only true if the window sill is more than
122.5 meters above the ground ... about 402 feet, or 40 floors.
If it's lower than that, then the flower pot hits the ground in less
than 5 seconds, and its speed at the end of 5 seconds is zero.
By the way ...
-- It makes no difference how much the flower pot weighs.
All objects fall with the same acceleration, and hit the ground
at the same time.
-- 5 kilograms is a mass, not a weight.

A. True
Solid substances can indeed exist in more than one form, a phenomenon known as "allotropy" or "polymorphism." In allotropy, the same element or compound can have different crystal structures or arrangements of atoms in the solid state, resulting in distinct physical properties.
Common examples include carbon, which can exist as both diamond and graphite, and sulfur, which has multiple crystalline forms. These different forms of solids can have different properties, such as hardness, density, and electrical conductivity, even though they are made up of the same chemical elements.
