Answer:If an atom loses or gains a proton, it becomes a new element. For example, if a sodium atom loses a proton, it would become a negative ion of neon. ... In nuclear reactions, like nuclear fusion, the electrons play minor roles and it is the nucleons that interact to create new elements
Explanation:
Answer:
2 r
Explanation:
Given that:
Radius of basketball = 9inches
Unknown:
Hoop's circumference = ?
Solution:
To solve this problem, we use the formula for the circumference of a circle.
The shape of the hoops is circular.
Circumference of a circle = 2 r
R is the radius of the basketball hoop
Answer:
25.157 cm³
Explanation:
Data Given:
Mass of Sugar (m) = 40g
Density of sugar given in literature = 1.59 g/cm³
Volume of Sugar = ?
The formula will be used is
d = m/v ........................................... (1)
where
D is density
m is the mass
v is the volume
So
Rearrange the Equation (1)
d x v = m
v = m/ d ................................................ (2)
put the given values in Equation (2)
v = 40g / 1.59 g/cm³
v = 25.157 cm³
volume of 40 g of sugar = 25.157 cm³
An element has no charge so its protons must be balanced with its electrons
so if X has 82 protons then it must have 82 electrons so that the atoms sum of charges adds up to 0
hope that helps
